In the old days there was the good old *.ls3 listing one could edit. In the new stylepicker: how can you change a user style 's display. F.i. reel1.sty is marked "user" and called jazz in different columns, and i want to change that to folk etc. and edit the memo column at the right ... -F

The question is waiting for some answer from PG Music since the introduction of the new Stylepicker in 2016.
As far as I know, category, genre, etc are derivated from *.ls3 files.
For ex. if in a ls3 file ,you have a SW feel for a given style, this style will be listed as Jazz in the Stylepicker.
