Must have. Rated 5 out of 5 stars
I'm using this since ~1,5 years now. Never got a single problem. Works perfect for me, I get notified about important mails sorted into a special folder only. No more distraction by notifications about low-priority mails. :-)This review is for a previous version of the add-on (0.14.6). This user has a previous review of this add-on.
