Unnecesary changes from musescore 3 to musescore 4

The new musescore 4 is great, has a lot of new features and made a lot of actions easier to find.
But there are some things that Musescore 3 had that were much better than musescore 4.

The biggest example is the possibility of making the tools window (the one on the left) smaller. I miss that so much!! With the tool window so big I feel like I'm losing a lot of space, it's so unconvenient and distractive!!

Do you have more of these ones?
