Except that this has introduced another problem. I noted the problem in the thread for the beta in February:
it’s a problem that @shotcut says he hasn’t found a fix for. In any case, you have to keep repositioning the mouse over and over again as you zoom in so it’s all more work which doesn’t allow for quick a zoom in and out of the timeline.
It’d be far easier and make much more sense if the zoom was just the standard as it is with pretty much every editor: The zoom always focuses on the playhead no matter where it is.
