Stretchable Mixer controls

Hello all! This is an extremely small feature request that probably not many will notice but I believe that it would be nice if the current MS4 mixer was stretchable and secondary screen dockable. Musescore 3 was able to stretch and shrink the mixer by just grabbing the outer edges. This feature allowed for more precise mixing and made the mixer much easier to see in general. And since I personally use a secondary screen on my setup, I like to be able to have the mixer open at all times whilst still being able to see the full score in front of me, and while musescore 3 was able to stretch the mixer, it still wasn’t able to dock. so if I could dock the mixer in the secondary screen and have it stretch to full size, I believe it would make things easier to use and better to look at/see. As I said, very small change and doesn’t do much to the overall app in general, but I still think it would be nice.
