[Users] Move thread to folder

[Ben Hancock]

Hi Claws Users,

With a collapsed thread selected, is there a way to move all the
messages in the thread to a folder (other than Trash)? The behavior I
seem to see is that doing Ctrl+O moves only the first message in the
thread to the folder, leaving the others in place. 

Of course, I can expand the thread and select all the messages
manually, but it would be handy if I could do this all in one go.

Thanks,
Ben
