Feature Request: Add more means to zoom in Piano Roll Editor.
Currently, without a mouse, there is no way of zooming in or out in the Piano Roll Editor. Since many people use Musescore on a laptop without a mouse, it makes sense to provide other means for zooming. To be consistent with the rest of the app, I suggest that Piano Roll Editor adapt the same keyboard shortcuts-- ctrl + for zoom in, ctrl - for zoom out, and ctrl 0 to reset zoom to 100%--add trackpad pinch zoom, and the ability to enter in the zoom level in the upper horizontal settings bar. The above suggestions would make the Piano Roll Editor more accessibility and laptop friendly.
