I see asymmetry in UI for file actions icons. This should be improved

github import doesn't work anymore
all cases when we add subrootfolder
also, I connected to remixd with a long folder list I can't scroll to the end

The remixd issue was always there @LianaHus and is not the result of anything done in this pr. I fixed the issue I think you are referring to with the padding with sub folders.

could you please add pb-1 on a span for menu items?
my other comment about remixd is fixed in my pr.
