Rated 3 out of 5 stars

I installed this hoping to apply more complicated filters than TB natively allows, and to apply filters to folders other than the Inbox.

I prefer to filter at server level and fine tune at PC level. The code by another reviewer (Can delete a message automatically without sending it to the trash) works brilliantly. I wanted to apply that filter to mail already sorted by the server into the Spam folder, but the 'folder name' filter doesn't work, as mentione din another review, so although the code works, I cannot apply it to the Spam folder, only the Inbox, and to do that I would need many, many key word filters to identify all the spam (by filtering spam on the server, it happens in the background with no load on my PC, unlike running multiple key word filters on my PC).

Another thing I wanted to do was to add and remove text to the subject. It allows text to be added, but not removed which is a shame.

Overall, good idea but not quite there for me. Maybe the next update?

Edit
I made a couple of posts on the author's site, asking how I could achieve my aims using this add-on. After a week, the posts haven't been approved which I assume means he hasn't read them. Support wouldn't seem to be a strong feature of this add-on, based on my experience. But I wish him and users of this add-on the best of luck anyway because TB could benefit greatly from better filtering.

This review is for a previous version of the add-on (1.2.0).  This user has other reviews of this add-on.
