A little tip for the curious:
when you open #ArtCraft (not the Launcher), you're prompted to login and/or create an account. If you just want to take a look, go right-click to inspect and toggle the visibility of the login overlay.
With my curiosity satisfied, I can say that I find ArtCraft utterly useless, and the people behind it pretty shameless that they want your data – and money for a data plan! – after ripping off other people's software.
And no, I'm not an Adobe defender.
