 Ordered list of TODOs:
 
-- introduce wmiisetsid to prevent crashes of not-setsid'ing processes like acme
-  which send SIGHUP to the complete process group (oh dear, Uriel that is really
-  retarded behavior by p9p)
 - introduce empty views
 - apply the focuscolor patch by Stefan Tibus
 - remove swapping action, merge vertical swapping into moving - is this a good idea?
