You may be missing the Favorite's and User's Categories. These are custom lists of preferred Styles created by Users. They can be opened from the Chord Sheet without having to open the StylePicker.
Also, personal memo's can be attached to any Style in the StylePicker. The Personal memo may be overwritten if that particular Style is updated for some reason by PG Music developers but the User would just re-enter a memo if that happens.
Thank you for the kind reply.
I did see the favorites and I have been using them. However, some styles I know I had set as favs did not survive the last update. Either that or I have duplicates that somehow are not showing the fav tag and have very similar names.
I did find the user categories. I guess I was looking for something a bit more visual. BIAB interface always reminded me of how MS Excel looked on my Mac Plus in 1990.
I'll try the User categories again. I created one, but I forgot why I stopped using them.
