Rated 5 out of 5 stars

Excellent add-on! And VERY light. Good job!
One suggestion: a "multi-row tabs" feature would be most welcome

This review is for a previous version of the add-on (0.5). 

Multi-row tabs

I myself never use "multi-row tabs" feature, so it is not planned at present, but I may consider it in the future. It would help if you could provide detailed points of "multi-row tabs" feature.
