Rated 4 out of 5 stars

First of all, thank you for making such a great addon (Vertical Tabs).

I wanted to request a feature which I think would be useful for everyone.
Can we have another button called 'Sort Tabs', which will sort the vertical tab list on the basis of the URL (alphabetically).
That way I can easily group together all scattered tabs of same website.
Also presently I don't use "group" facility much. But if I am able to sort all my tabs, then I can group them as well easily.

This review is for a previous version of the add-on (0.8.1-signed.1-signed).
