afaik, even with the extension it only affects the editor pane - any other windows still require tons of mouse use. I'm not mouse-nazi, but years of one-handed use of it have created tons of problems for me - in the neck, wrists and my back. All kinds of mice I tried didn't help - magic trackpad, vertical, ergonomic, etc. I'm sure this is pretty common.

I keep thinking of maybe I should learn to become ambidexter mouse user, and if I ever have to become a VSCoder (I pray not), I still may have to. For now, Emacs and vim and reduced mouse use are working.
