*-palette can't tell when an iconified window has been created. I
don't see any easy way around this, given how SubstructureRedirect
works. Possibly CreateNotify...?

rxvt (but only an rxvt spawned via Button3 or *-panel) dies if you
kill aewm with ^C. kill -INT is fine. Arrrrgh. I think this is just a
Unixism, or an rxvt bug (twm does it, anyway). Hopefully I am the only
one to use ^C...

Support for WM_COLORMAPS remains to be implemented. It should be
relatively easy. OTOH, even though our colormap handling sucks, I
haven't gotten any comments on it, which supports my theory that no
one uses 8-bit visuals anyway. ;-)
