Rated 3 out of 5 stars

The add-on is *very* useful and allows me to easily set up reminders to follow-up on some email.

Unfortunately, when the add-on is enabled, some of my mailboxes can no longer display the emails in their folder. When I select a folder, the email list is shown briefly (for 1-3 seconds), then the list goes blank. Saved searches work as workaround, yet I have no idea how to debug this.

This review is for a previous version of the add-on (0.7.9.4).  This user has a previous review of this add-on.
