Rated 4 out of 5 stars
Just started using this extension. Seems to work OK.
Would be more confident if it was more heavily used and reviewed by other people and if it supported permissions so I had more confidence it did not leak any information.
What I was really looking for was an Add-On to provide a filter field for the folder pane. My list of folders has become rather unmanageable. The advantage of a filter field is that it I may not completely remember the folder name I am searching for, or there might be multiple similar ones. e.g. if I typed "ship" into a filter it could list "Shipping" and "Transfer-shipping" folders while this Add-In would just take me to "Shipping" and I would not be reminded of the alternative.
