Rated 5 out of 5 stars

Tremendous productivity booster - makes moving emails to folders SO much faster, through single-letter shortcuts or spelling out the (sub-)folder name.

This is on top of my wish list for new features in TB proper, also to save the sanity of opto: he's a hero fighting against continuous TB API changes, and it would make so much more sense to have upstream deal with a core feature such as this.

This review is for a previous version of the add-on (4.1.12).
