That's pretty much what I have in mind. I have a rough idea of how to do 
this - essentially introducing some indicator of level into the events - 
and I think I can even get it to perform reasonably well. But without 
changing the core event structure, it won't be much better than a kludge. 
I'm still unable to build timeline from scratch, so it's going to be 
difficult to do this.

I know about handling some of the events, and drawing and hiding 
tracks/bands, so I'm not totally in the dark. But what I'd really like to 
do is build some infrastructure that I can use to make subsequent projects 
easier to do.
