It's pretty good, but I wish it would make the entirety of Google Docs dark, and not just the documents. If the Google Docs dashboard was also dark, that would be great! Still though, it's really good. My eyes can finally rest easy on the dark background.

Some of my other critiques are, the highlights do not show up at all, even if they are white or yellow. Comments no longer have their highlights.

This add-on is really good though, don't get me wrong. It just has some kinks to iron out.
