So for kicks and giggles I have compiled bmpanel (
nsf.110mb.com/bmpanel/). However, while testing it, I discovered that it really only works in fluxbox, openbox, and icewm. (I didn't try metacity, but I presume it would work.) Because it needs a NETWM-compliant window manager, it does not work in aewm++, evilwm, flwm, hackedbox, windowlab, or tinywm. Well, it works, but all it shows is the panel and the clock; no workspaces or taskbar, which in my opinion makes it rather useless. (I didn't test to see if the systray worked.)
So, it is still worth submitting it as an extension?
