Rated 5 out of 5 stars

Don't create your own skin. Try to blend in with the theme the user has chosen, to use its style. Now you just make the buttons look like in default theme.

It is as helpful as possible, but I still don't know how to make my extension work correctly.

Hide duplicates is a great feature.

This review is for a previous version of the add-on (0.6.1).
