Description

It's nice to have an ability to highlight all found matches. When I press N/n I would like the highlighting of a current match to be changed.

Great suggestion, as of now i prefer to use Firefox's ctrl-f because that has the highlight all option and Vixen doesn't.

This would be an useful feature. I hope it does not impact performance.
