Thunderbird's behavior is illogical when moving a message from one Gmail account to another. It copies the message from Account 1 to Account 2, and then it archives the message in Account 1 instead of deleting it.
The correct action is delete, not archive. "Moving" means move from one place to another, not create a copy so that two versions begin to exist in two different places. If the user wanted to copy, he would choose copy instead of move.
Unsuspecting users use the move command without knowing that Thunderbird is actually archiving their old messages instead of deleting them. In other cases, people like me, who know that Thunderbird doesn't "move" correctly, sometimes can still select "move" instead of "copy" by mistake. The result is that you have to fish for those archived messages in Account 1's "All Mail" folder now, and if you've moved many emails that were buried deep inside the inbox, you are screwed!
This is a UX disaster. Why has this travesty gone on for so many years and why hasn't it been addressed after almost 2 decades?
