Creating filters with this extension is intuitive, painless, and fairly fast.The downside is that only IMAP is currently supported. Earlier versions supported both POP3 and IMAP.
This review is for a previous version of the add-on (0.0.3).Hi amber,
thank you very much for your review.
I've created an issue https://github.com/gark87/SmartFilters/issues/2 based on your review.
It will be fixed in next release.
