It would be great to have horizontal scroll control (or faster because it's too slow not as fast as in premier or pro tools) (not everyone has an Apple mouse. (that mouse is uncomfortable for me)).
It also would be great if we have a horizontal zoom as we have with Alt + scroll wheel. because navigation on horizontal is more important.
Also It will be great to have Hand Tool like in after effects by holding space for a long time. it will help to move and navigate better. (I figure out that it's on scroll button but would be good as well on long press on space)
