Decreasing the spacing between two staves
There seems to be a limit on how close two staves can be. I want them to be closer. This used to work fine in Musescore 2, where you could hold shift and drag an space of the other stave closer and closer to another stave. In Musescore 3 this is not possible, and even changing the stave setting "Extra distance above stave" to a negative value still produces a limit which is unsatisfactory and does not work.
