Good one, could you please eleborate on this some more (seperate discussion), 
i.e. the way you want to see it work, ways to toggle behavioral and so on?
Like: keep the playhead centered, or flip pages by 1/2 the page width, or with 
smooth (accelerated) scroll, so you will always be able to see the playhead, 
not that it suddenly jumps from the right end to the left end of the view, 
ideas suggestions ....

OK, so during playback zooming works on the playhead, makes sense.

Oops, I meant, vertical only for the track it is upon, horizontal obviously 
works always on all tracks.

Just popping in my mind, what about: [ Z ] and moving mouse is omnidirectional 
zoom, [ Z ] + mouse scroll wheel is vertical zoom for the pointed track?

Another point, vertical track sizes, analog, ie non fixed sizes, or with fixed 
steps (like small, normal, large, huge).

Sure, keep them comming, the more ideas the better!
Eventually, they all can be added to the Zoom class, so one can configure the 
behaviour the way he likes the most!

Just for the record, [ Z ] + right mouse click -> opens options menu, some 
sort of dialog, an animation of the 'hold cursor', you name it, it's all 
possible!
