>> OK, I promised Jon McCann to write a mail here giving information on
>> my thoughts on removing the minimize and maximize buttons since I've
>> been resisting the request of the designers to remove these buttons.
>> My main objection to removing them has been that I didn't think we
>> really understood the use case for minimization, or how we would
>> satisfy that use case. The pattern of use for minimization is that a
>> lot of people don't use minimization at all, and other people use it
>> extensively.
>> It didn't make sense to me to remove something that we don't
>> understand with idea that we'd add it back later if it turned out to
>> be needed. To make people suffer, and have it be a major focus of the
>> GNOME 3 transition, then go and add it back anyways.
>> On the other hand, if we do have a reasonable sense that we have
>> workflows that basically will work for everybody, then I'm more
>> comfortable removing minimization. So, this mail is reporting on my
>> attempt to come to a better understanding of minimization and how it
>> fits in with the GNOME 3 workflow.
>> Why do people minimize windows?
>> ===============================
>> I think the first thing to realize is that minimization doesn't make
>> sense if you maximize everything. If you run everything maximized,
>> then it just doesn't enter in ... switching between windows is
>> switching between windows. (I personally typically maximize
>> everything, so I don't minimize windows.)
>> Reasons people minimize:
>>  * Because they like a tidy desktop. I think a lot of people are
>> uncomfortable with a desktop where the window the are working with is
>> overlapping other windows - where they are looking at a "gigantic pile
>> of papers". These people like working with a few windows on a clean
>> desktop. But they still have a larger set of windows open for less
>> immediate tasks.
>>  * Because maximized windows interact badly with unmaximized windows.
>> If I have a task that involves looking at multiple unmaximized
>> windows, then I switch to a maximized web browser, getting back to the
>> other state is hard - I have to select each window in turn without
>> accidentally selecting the maximized window again.
>>  * To find a window behind other windows - if you generally select
>> windows by clicking on them, and can't see the window or windows want,
>> minimization can be a way of getting a big or maximized window out of
>> the way and working with the windows underneath.
>>  * To "save windows for later" - if you open windows to represent
>> tasks, like responding to an email or reading a PDF of a paper, you
>> might not want them directly in your face interfering with the work
>> you are doing first.
>> Are workspaces a replacement for minimization?
>> ==============================================
>> Since minimization is basically about wanting to work with a subset of
>> windows, workspaces are clearly related to them. As compared to
>> minimization they have advantages and disadvantages. The advantage is
>> that they are stable - that is, I can have one workspace with a
>> terminal and an editor, and another workspace with a web browser and
>> my mail program and they will always stay that way - I won't lose the
>> grouping. The disadvantage is that it isn't flexible - if I need the
>> editor and web browser open at once then I have to go to the
>> Activities Overview and move the web browser, and then my web browser
>> and mail program can't be open at once until I move it back.
>> Experiences with removing the minimize button
>> =============================================
>> I asked the two people on the Red Hat GNOME Shell team who I knew
>> heavily used the minimize button to try removing it and report back to
>> me about their experiences. (These obviously are not typical users
>> using typical applications, but they provide some data about how
>> people actually use the minimize button.)
>>  Marina:
>>   Marina generally used the minimize button when switching between a) coding
>>   on the shell with non-maximized terminal and editor windows b) doing tasks
>>   in a maximized web browser. She would minimize the web browser
>>   to get from a) to b) and then use the overview to get back to the minimized
>>   web browser.
>>   When she turned off the minimize button, she was initially very frustrated
>>   because she kept going to where the minimize button was but finding only
>>   the "useless" close button there. She then turned off the close button as
>>   well and was much happier with the result. [I don't think this is
>>   really an option however - there are going to be too many cases where apps
>>   are designed expecting a close button.]
>>   No problems were reported with:
>>   - Having the maximized web browser window still visible under the coding
>>     windows... this was reported to not be distracting.
>>   - Having to separately activate the editor and terminal windows from
>>     the overview.
>>   Workspaces were found not to be useful because they didn't allow to
>>   easily switch between working with a fullscreen webbrowser, to
>>   using a non-full-screen web browser in conjunction with an editor for
>>   patch review.
>>  Dan:
>>   Dan normally keeps xchat, terminal, and emacs in a fixed layout,
>>   and then uses unminimization and minimization to temporarily switch
>>   from the terminal/emacs task to mail or web browser tasks.
>>   He also uses minimization to save web pages opened for patch reviews
>>   for doing later.
>>   Dan reported that he was able to successfully switch to a setup
>>   where web browser and email were on separate desktops. He didn't feel
>>   it was an improvement, but he also didn't feel a strong urge to
>>   go back to the previous setup. He did report feeling isolated when
>>   on a workspace with only web or only email.
>>   Dan often opens links in separate web browser windows, so to do the
>>   patch review tasks that frustrated Marina's use of workspaces, he would
>>   open the review link from email in a separate window and then move
>>   that window to his coding window.
>>   He found after using it for a while that the most effective way
>>   to save windows for later use was to reserve a desktop for that
>>   and move windows to be saved to that desktop.
>> Problems with current minimization
>> ==================================
>>  * Many people (most people?) never minimize. So one of the most
>> prominent permanent controls is something that has no particular
>> function but makes your window vanish if hit accidentally.
>>  * There is no real mental model for what happens when hiding. The
>> window shrinks off to the corner, but when you go back to the
>> overview, it's still there and looks the same as if you hadn't hid it.
>>  * The minimize icon is a remnant of the GNOME 2 taskbar and has
>> nothing to do with the GNOME 3 experience. (Really, we don't have
>> minimization at all, we have "hiding")
>>  * Having minimize and maximize controls puts "stress" on the concept
>> of the centered title - the titlebar looks unbalanced.
>>  * If people are using minimization within GNOME Shell as an
>> alternative to things that could be done with workspaces, then we have
>> to design other components for two different workflows - the
>> minimization workflow and the workspaces workflow.
>>  * Minimized windows break the illusion of zooming to the overview.
>> Is removing the button really removing minimization?
>> ====================================================
>> You can still minimize with:
>>  - Right click on titlebar to get to the window menu
>>  - Alt-right click on window contents to the window menu
>>  - Alt-F9
>>  - Alt-space n
>> But, no, for all real purposes removing the button is removing minimization.
>> Could we design an improved "hiding" model
>> ==========================================
>> I think there are some things we could do that would make minimization
>> less weird.
>>  - Maybe use a different icon
>>  - Reserve a space for minimized windows in the overview - perhaps
>> something like:
>>    +--------+ +-------+
>>    |        | |       |
>>    +--------+ +-------+
>>        +---------+
>>        |         +
>>        +---------+
>>      +---+ +---+ +--+
>>      |   | |   | |  |
>>      +---- +---+ +--+
>>   So then the other windows would smoothly animate to their overview
>> positions and
>>   the minimized windows would just "be there" in the overview.
>>  - Animate minimized windows toward the reserved space instead of
>> towards the corner
>>   (we could even show the minimized windows on the background of the root window
>>   in the main view and return back to the days of twm???)
>> But at this point, we're out of time to experiment with anything for
>> GNOME 3.0. Also this doesn't address minimization being unused by many
>> users and having two different workflows for working with a subset of
>> windows.
>> The maximize button
>> ===================
>> The above was about minimization - but the request was also to remove
>> the maximize button. This is a little different since there are more
>> obvious ways to maximize a window - the drag to the top gesture or
>> double-clicking on the title bar - we're not really talking about
>> removing the feature of maximization but just the button.
>> I don't think it's generally a big deal to remove the maximize button.
>> Trying it myself, I did find one problematical area - it's pretty hard
>> to distinguish between a mostly maximized and maximized window but
>> they behave quite differently. I think there are some adjustments we
>> could make to help with that - one one in particular is making sure
>> when you unmaximize we actually shrink the window by a significant
>> amount and don't leave it screen sized.
>> The way forward
>> ===============
>> I'm going to openly admit here that I'm a bit uncertain.
>> Until we got the new workspaces controls, removing the minimize button
>> was impossible; it took away a workflow, and left only a very hard to
>> use alternative. With a better model for working with workspaces,
>> there is evidence it might work, but we're working from a very limited
>> data set and we don't have much runway left to adjust before GNOME
>> 3.0.
>> Other considerations against removing window controls: no minimize
>> leaves us further away from Mac and Windows and removing the minimize
>> button in the fallback mode would work much less well, since the
>> overview isn't available to quickly and conveniently switch to a
>> hidden window.
>> On the other hand, if we leave minimization, we have something that is
>> clearly undesigned and unfinished. And we portray the taskbar as
>> something that is missing rather than something that is unneeded,
>> because we have a window hiding icon that was designed for minimizing
>> to the taskbar.
>> In the end, I think with GNOME 3 we need to emphasize design coherency
>> and slickness - what is different and better, and that actually is
>> more important than being 100% sure we perfectly meet everybody's
>> workflow. Having half-designed minimization is going against the goal
>> of coherency. And doesn't provide testing of alternate workflows. So
>> I'm going to remove the minimize and maximize buttons for GNOME 3.0,
>> and if it doesn't work out, we'll eat crow, design window hiding
>> right, and add it back for 3.2.
>> Feedback?
>> =========
>> If people want to give their thoughts here, that's fine, but I don't
>> think a mailing list debate is the best way to come to a decision, so
>> the decision above should be considered basically final for the 3.0
>> release.
>> The real form of feedback that we need going from GNOME 3.0 to 3.2 is
>> careful observation of how users are using GNOME 3 - are they figuring
>> out how to use the overview and workspaces and message tray as we
>> expect them to use them, or are they doing cumbersome workarounds
>> because we took away essential features.
