Rated 5 out of 5 stars

I'm a big fan of Google Inbox and use this addon as the closest analog.
It's almost perfect for me, just needs a few enhancements:
1. Add the timespans like "Next monday at 11 a.m."
2. Change order of User defined timespans (like Move Up/Move Down)
3. Maybe hold the resubmitted messages in a virtual folder.
THANKS a lot!

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