CloseReview for MailClassifier by Stanimir Stamenkov
Rated 4 out of 5 stars
Great extension. I would love to see it built-in.
I think it just lacks "Classification -> Clear" option to allow clearing of the false results, and then bulk move the rest.
I guess explicitly stating certain messages are not of any of the available categories could improve the filter, also (just like with the junk filter).
