Review for Quick Folder Move by Olav Seyfarth
Rated 5 out of 5 stars
The hotkey Shift-M is very handy. Swiftly file your messages.
I'd love to have advanced functionality though, like a "best guess" that can be accepted by Shift-M+(read-the-suggestion)+Enter. And 1.6.1 doesn't accept space - why? That's a normal character used in many of my folder names.
It's a pity the AddOn is not (yet?) compatible with TB68.
