Task Manager settings: grouping & sorting

[Martin Kho]

In Task Manager Settings - right click the Task Manager - it's possible to 
set:
A. Grouping to: (1) Do not group, (2) Manually, (3) By Program Name (default)
B. Sorting to: (1) Do Not Sort, (2) Alphabetically (default), (3) Manually, 
(4) By Desktop.

When two instances of an application - eg 2x Konsole - are opened, with the 
default (A3+B2) settings, they will appear in the Task Manager as one button 
with a little "2" at the right. Clicking on this button, pops up a box where 
you can choose between the two consoles.

Next, in Task Manger Settings leave Grouping the same and change Sorting to 
Manually (A3+B3). Now, no box pops up when you click the 'Konsole-button'. 
It's not possible to choose between the two consoles. 

Is this a bug or just by design?
