Dynamic zooming without clicking on an "event" would be a game changer.
At present, scroll wheel just goes up or down through the tracks.
I know you can use the "modifier" keys (Alt, Ctrl, Shift) to do other things.
It would be helpful and faster to just click on an area or just hover over a portion of a track and use the scroll wheel to zoom in to that area.
The more you scroll, the closer it gets. scroll the other direction to zoom back out.
