Rated 5 out of 5 stars

simple, effective, - no more to say
I'll be extremely happy if I'll have also one "checkbox" not checked by default for IMAP accounts - moving folders on IMAP could produce problems
It is safest to create destination folder and move emails rather than move the folder

This review is for a previous version of the add-on (1.1). 

Could you explain more what you see this feature accomplishing? I don't quite understand what the checkbox is you're referring to. Thanks for the positive review.
