Ah thanks for clarifying that. That does seem like a useful feature. If there isn't an option or plugin for this already, it sounds like relatively low hanging

Ah thanks for clarifying that. That does seem like a useful feature. If there isn't an option or plugin for this already, it sounds like relatively low hanging fruit. Might even be a good first project for someone who's interested in contributing to tbird. As an aside, back in the days of dialup, I would compose a batch of mails offline, give them all a read-through, and then connect and send. My mails contained significantly fewer errors back then.
