I also have deferred update to TB60, because I don't want to lose the features offered by this add-on.

I use Quicker Filer every day, and it's great:
1. Hit your keyboard shortcut.
2. Type in some (partial) words to find your folder
3. Press enter to file and... Boom! Done!

I did try the Quick Folder Move, but it lacks the search capabilities of multiple words (regardless of order in which they are input). For instance, with Quicker Filer I can search for a folder like 'GMail Server/Projects/123456-Customer-DoorRepair' by just entering 'proj door', and it would narrow down all possible folders/subfolders that match those (partial) words. Very quick way to file emails!

All other tools I've tried so far, allow only one-word matching, or you have to do the search in several steps, which I thing defies the purpose of "quick" filing.

Would love to see if Eivind Rovik comes up with a new version compatible with newer versions of Thunderbird.
