I was thinking about the wallpaper swapper built into the menu... In the development test releases, there is like only one desktop icon replacer that actually works. There is also the portableapps icon application, but that is only one icon, and it isn't really an icon at all.
What would be nice is if Mr. Haller could somehow add something like the wallpaper swapper, but more advanced, almost to where it creates a whole new "desktop" folder. It would have:
1) a background - perhaps it could be as easy to set and change as the menu picture is.
2) icons - you could simply right-click one of the apps on the menu and select "make shortcut" or "make icon" or something like that, and it would appear on the new desktop. you could also just click and drag an icon like normal, and the platform would remember where they were moved to. The "hide desktop icons" option in the platform now could be expanded to include (with check boxes, so you could select multiple options) "swap icons" and "swap wallpapers."
3) perhaps it could mess with the menu bar (start bar, task bar, whatever that's called) and make that your own too...
Parts of this might already be in the process, but this is what I have been looking for for a while and would be happy to see it...
