This is an idea I've gotten from seeing dozen of fvwm screenshots in the monthly Desktop Screenshots topics at the Gentoo Forums (http://forums.gentoo.org). The idea is to have thumbnails of minimized windows placed on the desktop (look in the top left corner in the download). I've been searching up and down for a similar function or program for KDE, but with no luck. I think I saw somewhere someone said that this could only be done in fvwm (don't remember why though) but I'm positive this can be done with KDE as well.
I know that thumbnails of windows can be created, look at kpager2 (http://www.kde-look.org/content/show.php?content=7120) or Taskbar v2 (http://www.kde-look.org/content/show.php?content=16261), both of these small applets have a mouseover effect where a small thumbnail of the window pops up. You can also have it in the kasbar.
I also know that stuff can be drawn on the KDE desktop, i.e (super)karamba does this, and that actions can be performed on this items.
The thing I don't know is how to create a program that would do this, and this is where you, whoever might be reading this, comes in. If anyone knows how to implement this idea, or know someone who can, or will help me getting started (or already knows about someone who is implementing this :) Well it could happen) I would be very grateful (or maybe Krateful :)
