Cannot change instrument name or hide them in parts
In version 2.x it was possible to change long and short instrument names from the parts. It was also possible to hide instrument names on individual staves, both in parts and scores. This is now impossible in version 3.
From a part:
- Right click the part name or staff and select Staff/part properties
- Change the long instrument name
- click OK
Result, nothing changes, if you open staff/part properties again the change is undone. If you do it from the main score, both the main score and parts is affected.
