I use this extension everyday to keep correspondence well organized. One aspect that could be improved is the finding of sub-folders. Currently, if a sub-tree of folders is collapsed, the extension won't search for any folder within the sub-tree. I have to manually expand a sub-tree and then type the folder name again. Also, the search algorithm only searches folder names that BEGIN with the typed sequence, rather than folders that have the sequence anywhere in the name. Thus, a search for A7 will not return a folder named BA7. I'd like to see this extension use a search algorithm similar to the one in Quick Folder Move 1.2 by Philipp Kewisch, which returns a list of sub-folders partially matching a search term and regardless of location in a folder tree.
