Rated 5 out of 5 stars

Hello and thank you for this very useful addon.

Currently, however, the addon is useless with a Gmail IMAP account.

Indeed, as explained by a Google engineer in this post
http://lifehacker.com/314574/turn-thunderbird-into-the-ultimate-gmail-imap-client
the Google IMAP engine:

1/ ALWAYS copies sent mail to the [Gmail]/Sent IMAP folder, whatever the settings in the email client.

2/ keeps a SINGLE copy of each email (even it is "copied" to other folders), with the following result: if you copy a sent email to some target folder, and further delete this email from the [Gmail]/Sent folder and empty the trash, then this email will ALSO be deleted from the target folder!

Thus the only way out seems to MOVE the email from the [Gmail]/Sent folder to the target folder, AFTER it has been sent.

Any chance you implement this in a near future?

Thanks in advance
