how to consolidate gnome panels

[Gianluca Cecchi]

Hello,
by default with Fedora you get Gnome configured with:
- the top panel with "Applications, ..." notifications, ecc
- the bottom panel where there is trash icon, workspace switcher and
open windows information (to minimize,restore, ecc)

I would like to have a configuration with only one panel at bottom
with the information of both.
I can move the top panel down and get the trash icon and workspace
switcher inside it, so that I can delete the other panel.
But I don't know how to change display behaviour for windows
information and where is this setting stored (aka where to configure
which of the existing panels has to display it..)

Anyone?
Thanks in advance,
Gianluca
