It's cool and all but it should definitely change the color for the tab pop-out because it just defeats the point of the extension. It's very contrasting with the black/gray (I mean, it is white) and it annoys me. When I'm trying to focus on my document, that pop-out just always draws my attention on distracts me. I like having the pop-out open, but I'll have to keep it closed because of how annoying and distracting the white is.
