I have been using this add-on for years, particularly the "On disk" flag which shows me whether messages in my IMAP folder have downloaded to the local disk. This has been a super useful feature. Unfortunately, the add-on is not working with the new Thunderbird release from mid-November 2018. I really miss it because I have now no idea about the synchronization status of my several Gb of E-mail.
I wonder whether an updated version of this add-on (or at least the "On disk" flag) could be developed.
Rock solid, I've been using it for years, albeit just for one feature that's probably considered minor: having a flag that turns on when a message in an IMAP folder has actually downloaded completely and can be displayed.
This add-on is the only one I could ever find that displays this information.
I can't believe I'm the only one that gets frustrated when I click on a recently-arrived message to discover that it's got a 10MB attachment and that TB won't display _anything_ until it's finished downloading the whole thing.
If you have some IMAP folders with a lot of messages that you do not need to search, this plugin will make thunderbird run very very fast. On a particular imap server I connect to thunderbird was unusable without this plugin. THANK YOU!!!
Great - real useful tool to eliminate that nasty indexing from junk and temporary folders! Should be a core feature! Indexing hundreds of mails each day in my spam folders is real nasty - so thanks for this.
This review is for a previous version of the add-on (0.3.1).
