Hi,
Just a proposal. I like to prevent selected programs (like xclock,
xbiff, xload) from filling up the taskbar (tint2 in my case) and added a
while ago a function that lets me set the EWMH flag
_NET_WM_STATE_SKIP_TASKBAR through a key binding (MS-t).
Also, since cycling in cwm can get hairy when there are a lot of windows
open, I added a function that emulates the EWMH flag
_NET_WM_STATE_SKIP_PAGER and assigned this to a key binding (MS-p) as
well.
The latter has proven quite useful for programs that one would want to
have hanging around - possibly with the sticky/frozen bit set - but
without interfering with the window cycling flow.
A somewhat crude diff included below for those interested.
