That’s one of the normal ways I do it. But for importing a whole set being able to drop it into a folder and just having it work like it did with the Pepe set would be amazing for brush creators.
So far the only downside I am seeing is that suddenly one has brushes outside of the typical asset library(ies) folder(s) which means an extra step as far as organizing backups is concerned. At least for me. There’s also the matter of organizing new brushes into the appropriate toolbar tabs which I’ve not tested yet with brushes dropped into the datafiles folder. I’m still wrapping my brain around that process already. 😀
