Copy is not copy but Move Rated 1 out of 5 stars

Archive This does MOVE better as it tells you which keys conflict with TB already assigned

But I did want COPY so tried Quicker Filer. I set up Letter X and Z with Copy and Instant Copy and when clicked a blank (well so fast unreadable but looks blank) message window flashes past and the email itself is MOVED to the folder not COPIED

Otherwise I'd like it

This review is for a previous version of the add-on (0.3.0).
