Hint markers with flat styling

I recently updated my Vimium styles to use a more flat look for the hint markers and I just installed Vimari for Safari.

@guyht What do you think of using something like this as the default? (Note that these screenshots are from Vimium since I had trouble getting my Vimari fork working locally)

No worries if you don't like this look. If nothing else, would it be possible to expose CSS styling overrides like Vimium does?
