Rated 5 out of 5 stars

First of all, thank you for this great add-on!

When I export a IMAP remote folder (in any formats: mbox, ecc.), replied and forwarded statuses of every emails are not saved (when I re-import the folder as a local one, blue and orange arrows are missing, and X-Mozilla-Status is set to 0001). I searched in the add-on github page (and over the Internet) but I couldn't find useful information about backing up IMAP replied and forwarded flags, so maybe there is something I'm missing.

Thank you again!
