Rated 4 out of 5 stars

without subfolders it's pretty hard to use this as an alternative bookmarks bar otherwise it would be 5 stars.

This review is for a previous version of the add-on (2.2.1-signed). 

Hi, thanks for the feedback. You are 100% right, we are totally aware of the limitations caused by the lack of subfolder support, and that is why this is our #1 priority for version 3.0 (together with a couple of other nice features...).
