Great, but please please please update for TB 68 and also restore all Markdown functionality!
Rated 5 out of 5 stars
This is the closest thing I've found to a Workflowy plugin for Thunderbird, and it's great! Unfortunately, I can't seem to get either check boxes or collapsible text to work any more with Markdown, but apart from that, 5 stars.
