I thought of something today when looking at a screenshot of a theme with the K menu open. The menu looked good and simple, with the games menu unfolded. The menu had about 4 games, probably just the ones the author used... Then somehow my mind thought "expose".
What if, when the user holds Ctrl (or something) while the menu is open, the unused menu items fade out and move to the bottom of the list, leaving brighter, frequently used items on the top. Then when the user let Ctrl go, it would shift back.
It would also add a nice layer of eye candy, as because the animation is all in the window, it's completely possible with today's KDE and QT!
Any ideas, comments on this? I know M$'s frequently used items menus in winME and win2k were hated... do the same reasons apply to this (i actually liked the ME and 2k menus)
