Flexible resizing of Layers panel

I often find myself fighting with the Layers and Masks panel, especially on a laptop. It would be helpful if there is more flexibility to how it can be sized.

Currently small is too small (shows only 2.5 rows), and Medium is often too big for my needs of about 5-6 layers except in rare cases, which results in a lot of wasted space and the scrollable area pushed down.

Auto size is incredibly stupid - it will create a huge Layer area even when there's only 1 layer!

What I want is to be able to arbitrarily resize it to my liking by dragging the bottom - just as you can do when the Layers panel is dragged into a floating window. Or an option to shrink to fit the number of layers I currently have by either expanding or contracting.There's so much other customization with the C1 interface it seems odd that this is still so primitive.
