>=3-track effects are a very interedting thing and I think we should keep them 
in mind, but I think a soluton thatworks with two tracks is difficult enough 
for the moment and will do till V1.0 ?

I like this idea _very_ much. I think it would be pretty easy to use, and even 
more intuitive than the usual "effect-track". Just make sure, that the tracks 
and the shaded 'transition-overlay-rectangle' have nice mouse handles to 
select/drag/resize them.
