I used Art Rage a lot on Desktop for over a decade and on a Surface Pro 4. I now have a Galaxy Tab S10 and want the features of AR I used on Windows. In particular, fully customisable brushes where I can set angle, colour, texture etc. Are these supported in the mobile versions? Or are the pens just the tools you get and the custom options not supported on mobile? The implication from the description is no, custom stamps and pens are not supported and things like a rainbow pen or drawing swathes of grass or a line of beetles isn't possible.
