Please fix whole rest alignment
If you delete notes from a measure, then change the rests to a whole rest, that whole rest is left-aligned. This also happens if you add a whole rest via right-clicking in note input mode. As far as I know, a whole rest should always be center aligned in an empty measure. It would be appropriate if this were default in MuseScore, rather than having to manually fix it with ctrl+shift+del.
