sounds like a very good idea .. can also be used as an effects TODO collector 
(see below for an example you raised)

ah, fond memories of smashing things into pieces :)

that's good stuff to know. i really like your idea of a wiki page to keep track 
of these things so that us mere kwin mortals know what can be done to help 
push things forward to the next stage.

ok; this isn't a big deal, more of a "nice to have". 

if we can sort out what already exists and works that's probably enough to 
chew on at once and will give great improvements (obviously that's why you 
started this thread in the first place, so i'm not saying anything new or 
useful there ;) and so things like cross-fade-on-stack-change can be put off 
for another time while we eat the low hanging fruit first. :)
