Very intuitive. But took me a bit to get use to the large split screen. Only problem was I had to disable it to get back to normal window. Perhaps because I'm using an older version of FF (v. 52.0.1 (64 bit) on Win 10.
Thank you for your feedback. But you really should not use old Firefox version with security problems… By the way, the next version of Bookmarks Organizer will require Firefox 57 or higher.
