Rated 4 out of 5 stars

Thanks very much for your most welcome contribution. Suggestions:
1. In the Alt-Q dialog, offer the previously-selected folder as default.
2. I agree with kastelrojo's point 3.
3. As with Quick File, add another hot key which immediately files messages to a pre-selected folder. This is useful when there's one folder you save a lot of your message to.
Thanks!
