Musescore 4 submenu mixer not docked
at musescore 4 last nightly version ( 2021-09-14 04:21 )
1) undock mixer
2) the submenu shows only at main screen.
This is strange when you get multiple screens and expect independency of the windows. Sorry if already reported :) Testing for the first time musescore 4 and damn it looks sharp congrats to the team!
hope posted in the right part
