Auto insert spacer by holding ctrl+shift+dragging

I have some ideas for working faster with musescore. When holding shift+dragging a staff down you can control the space between staffs and that works great and gives control.

1. Auto insert spacer by for example holding ctrl+shift+dragging a staff down. And maybe then there is no visual spacer needed any more because you can control it by just (ctrl+shift) clicking and dragging.

2. In complex pianoscores i need to change in a lot of places trailing or leading space in the inspector. Thats just inserting some numbers and then look how its looking. This could also work by click and dragging () on a notehead. Click and dragging gives way more control.

Cheers,
