Hmmm... I'm pretty sure you can give an email multiple tags on Thunderbird. Although, you run into an issue because some email servers don't support tag sync, so that might be creating an issue here. Or so I think.

In any case, best of luck with it!

On Gmail, I used their tags as what they appear on Gmail as, namely "virtual folders".

Thunderbird's tags are a different concept from folders on IMAP.

Ah, that is true. Got what you were getting at now :)
