0002791: Moving (or copying) compacted threads
When the "View Mode" | "Thread by" field is set to "References", moving (or copying) a group of messages, grouped under the same thread, has the effect of moving (or copying) only the first message of the thread. I'd rather expect that *what I select* is moved (or copied) where I want, that means everything which follows the selected message and which is "hided" by the '+'.
It is possible to affect an entire thread using the field "Thread" from the menu which appears right clicking on a message header. Nevertheless I think that moving (or copying) a not expanded thread should include in the operation all the messages of the thread. If I want to affect only one message I can expand the thread, select the desidered message, and move/copy that single message only.
