I really like the concept, and think it is a big improvement. Well done. I've also been experiencing the unresponsive menus on OS X. A permanent fix for that would be nice. Would also like to see customization.

This review is for a previous version of the add-on (2.1-signed.1-signed). 

We have various ideas to provide a good search suggestion experience. Because you're picking a category, the suggestions can be better than just any general suggestion for the letters you're typing.
