Vertical tabs mode new tab button should be fixed position at the top of the tab strip

I did some web searches because I was curious if others asked for this and wow, yes, a LOT of users want this! There are many more tweets and reddit threads where users ask for this but I can't link all of them here, it would take days hahaha. You get the idea, this is a very highly requested feature/complaint
