Again, I know this! And what I’m saying is that Krita already allows ‘copying’, technically.
1 if what you’re worrying is that my suggestion would encourge more people to ‘pirate’ brushes, I honestly think it’s an overreaction because it basically has nothing to do with how the application works. And no major painting application intentionally try to prevent the brush piracy from happening on this level as far as I know(Correct me if I’m wrong).
There are priced materials and priced brushes for sure, and all you have to do is just copying the original file and share it if you want to ‘pirate’ it. It doesn’t have anything to do with the application itself.
2 If it’s about more private, subtle usage like duplicating or making something new out of preexisting brushes, I can see why some people would feel that their work is getting stolen, but I still believe it would do more good than harm.
I’m open to further discussions.
