Bumping this as I've the same question ... I browse and audition many individual Realtracks across different styles, and apart from keeping notes in a text file, in BIAB 2020 I see no way of keeping track of which are my favorites, which for me is pretty much essential given how very many choices BIAB gives you. "Most recent" is nice but only for a short time. The ability to tag favorites is a quite basic functionality in library-type software. Is there still no way to do this in BIAB 2020?
