It simply used the little task bar thingy included in fluxbox (only one workspace configured), and the right-click menu. The menu was deficient for a while till I simply manually edited it to have the local language equivalent of "Audio Player" (simply Audacious in Winamp 2 mode), "File Manager", "Web Browser", "Terminal", "PC Shut Down" (had to give user read/execute rights to the halt command)
I guess that's "not LXDE" but it had pcmanfm, lxterminal and gpicview.
I don't remember what can be wrong with pcmanfm but it has one killer feature, besides tabs and somewhat being a better nautilus than nautilus. That's the "semi-automatic" mount of USB drives, which just plain works and does not do things in your back. No shit like "umm, is it mounted or not? and is my drive that /media/1eeb7453-ffd0a thing?"
