Rated 4 out of 5 stars

I've been using it for a few hours, and already v useful. Finally, I can unload that list of pending emails from my poor overworked brain.

I had to work it out how to use it by trial and error, and I'm still not completely sure what's going on: it ought to be self-explanatory in use (it isn't) and the documentation is unclear. E.g.:
a) I think you disable the reminder status by setting the date to today.
b) It's not clear what the "Days before expiration" in the Add-On Preferences relates to. Is it the time between when a reminder goes amber and red?

Personally, I prefer the simplicity of 2 states (red/green), not 3. Perhaps setting "Days before expiration" to zero achieves that. I'll experiment, but I shouldn't have to.

This review is for a previous version of the add-on (1.0).
