At present, by default, this is how small the Layer and Artboard panels' sizes can be minimized to. They take up a lot of valuable screen room on my Mac. I still want to see these but don't want to dock them into the side as that takes up a lot more room. Currently it's too invasive to my workspace, even so when I am using more layers and artboards.

I would suggest making it possible to make these panels even smaller so I can have extra space to be able to see more of my work and space that I could move other panels into without them overlapping.

There might be other panels that could also be minimized, however I have not looked into that
