Show mailbox in thread view

[kesselb]

Is your feature request related to a problem? Please describe.

The threading works across mailboxes, with trash and junk excluded.

I would like to know in the thread view where a message is actually stored.

Above is an example. One message in my inbox, the other one in sent. I would like to move the inbox message to a different folder.
