Have you tried adjusting the column width marker?
I don't seem to have this in the Windows version so I don't know if it can be adjusted or not (or even why it would be there).

I have the same issue with 20. The last update was said to fix it, but not for me. The column adjuster doesn't work, best I can tell. The odd thing is it was fine after migrating from 19, but started acting up after I did a re-install trying to fix something unrelated. I had to switch to icons, which I don't really like.
No real fix for the problem at hand, but have you tried using the 'popup' favourites from the toolbox icons/buttons? You can change these to list / 3D preview as preferred and you don't have another palette cluttering your workspace.
You can also get to the favourites fairly easily from the settings dialogue of all the tools.
