Zoom In/Out in MuseScore3
Zoom in with Ctrl-Plus doesn't work any more in the standard way for Windows: namely, Ctrl-= on the alphanumeric keyboard. In other words, it shouldn't be necessary to press Shift as well.
It's easy enough to fix using Preferences/Shortcuts to add Ctrl-=, but I hope Ctrl-= won't get used for something else!
Incidentally, I would be much happier if we could zoom in and out using the MouseWheel (point and zoom as in Google Earth). Getting the geometry right isn't hard. But of course, that should be an enhancement request.
