Rated 4 out of 5 stars

Hmm, I think you overlooked two arrows (triangles) on top, where you can change folder structure as you like, group by account or by same folders.

I wonder is there a way to sort conversations so newest one comes on top? I used to look my e-mail that way older mail down, new messages on top (it is more logical for me).

It can be sorted in thunderbird window, but i do not see it in conversation window?

This review is for a previous version of the add-on (2.0.8).
