Rated 3 out of 5 stars

Great idea, I like the simpler approach more than mailmindr, but the ext. has some bugs (I have TB 52.9.1):
1. The datepicker for reminder dissapears after Thunderbird restart. I have to disable and re-enable the extension to have it back.
2. I don't have the datepicker in message composer window.

And ideas for imporvement:
1. Add a meaningful label to date picker
2. Ability to chose own labels would be nice (or alternatively provide translated labels)
3. Apply also to threads

This review is for a previous version of the add-on (2.0.0b). 

Hi K M, thanks for the review. The current version is an intermediate one with limited features, see version comments.
1- datepicker disapearing : will be fixed in the next version (soon to be released)
2- same.

Thanks for the improvement ideas.
