Musescore 4 top-bar buttons

First off, I really really like the insane overhawl of Musescore, no need to mention it here.

What annoys me right now about it is some "wasted space" in the top-bar. I would love to have an option to remove the very top bar with the "home", "score", "publish", "parts", "mixer" button, as well as have the ability to dock the playback window next to the other toolbar elements at the right end. I think this little addition of space could come great, I personally really like to have UI take up less space on my screen.

How it is:
