The following is a random list of things (and applets) that may provide inspiration into gnome panel 2.0 (3.0?)
I think that the icons/launchers in the gnome-panel should have a margin of 2px on all the sides. It will make a cleaner and better user interface and user experience. It will help also to organize the icons in a better ways and get a kind of grid or constant space between each icon. Here is a mockup that i made for this propose. icons in gnome-panel needs more air around!
Desrts compositing panel work as a foundation
- D-Bus based interface instead of Bonobo
Play well with compiz widget support (like screenlets)
Group based window management - an idea for redesigning the panel and use of workspaces
A hypothetical perfect panel would be much similar to current, with the inertial-things-have-mass bling of akamaru physics engine (from kiba-dock), with the reflection and other gui touches from awn (or libawn).
There would be support for some of the cool touches in kiba-dock and awn such as stacks, and the ability to change ones dock icon (like you can in awn)
