The layer tree is a really great feature and very powerful. However, I find myself spending a lot of time scrolling horizontally to see all the info in the layer tree. This is especially true when your blocs have names, adding class names etc.
My wish: make the layer tree panel draggable so that you can adjust the width to be able to read everything. So something similar to Photoshop, Bootstrap Studio, etc.
Of course, it would probably also make sense to make the right panel with object info adjustable.
