[dwm] Re: a locked window for stalonetray - a different approach

[Marcin Cieslak]

Marcin Cieslak wrote:
Probably this behaviour could/should be combined with your "nofocus" 
feature, i.e. locked windows should never get focus *at first*.

And another version - allow the "locked" window to be normally focused 
with mouse or keyboard, but do not focus it as the *first* client in
the view.
