Multiple Rows for Tabs Rated 4 out of 5 stars

I would also like an option to use multiple rows. It's in TabMixPlus and other tab extensions, but I would prefer to use just yours. Australis won't be ready until at least Firefox 19, so it would be very helpful to have this feature before then. Thanks if you can!

This review is for a previous version of the add-on (3.0).
