well if that aint one of the most kickass desktops I've seen so far then I don't know what is. How did you manage to make it function the way it did (with clicking the bars and the buttons next to them, etc.)?
The code behind the function? Well, there's a lot of code in there, but the ones that triggers it are:
To open a folder: LeftMouseDownAction=!execute ["explorer.exe" "C:\Media"]
To open a bookmark: LeftMouseDownAction=!execute ["firefox.exe" "[link]"]
To start a program: LeftMouseDownAction=!execute ["C:\Programfiles\uTorrent\uTorrent.exe"]
I hope that answers your questions. If not, I'm considering to make a rainmeter pack out of this in the near future, which should be awsome as I've made several improvements on functionality. For example; Left clicking the bottom blue bar you start the current song, while right clicking it stops it. Left clicking the bottom red bar hides all text (by starting a screensaver which showes the wallpaper with color).
