I decided to delete my taskbars because they were in the way and ugly, so I switched to a middle click menu. I liked it much better. I'm currently using compiz-boxmenu, which is sort of a soft fork of openbox-menu with a couple neat little extra features.

Anyway here's a half-baked effort at a semi functional menu generator that you could use if you're using compiz as a standalone window manager. Enjoy!
