Review for Quick Folder Move by Pierre Langlois
Rated 5 out of 5 stars
This module is absolutely fantastic.
I have hundreds of sub-folders. With this add-on, I can effortlessly archive emails to the proper sub-folder. I wish I had found it earlier.
5$ are on the way.
The app could be improved by:
1. using arrow keys to navigate through the pop-up list
2. (maybe) showing the hierarchy of folders in the pop-up list
