Well, the bad side is that I had to edit config files to get the panel the way I want it (launchers, plugins, and menu items). I'm sure there is a GUI tool out there, but I'm not aware of it for the Z. The good thing is that Rox-filer and fbpanel are a great combination to get that "desktop" feel, if that's what you're going for. It seems to be equivalent to Matchbox as far as speed goes. I'm a happy camper. Soon I'll put up some screenshots (when I figure out how...)
If you see anything that could/needs to be changed in my .xinitrc file, please let me know.
