Would love a Roll brush in affinity photo, which is a brush where your custom brush shape is deformed along the stroke curve. Here's a video of the Zbrush "Roll Brush"... http://www.youtube.com/watch?v=eY2_EPG-zWY This is similar to the "Angle Jitter -> Direction", except this feature only rotates the custom brush along the stroke direction. The Roll brush actually deforms the stamp in that direction. This would let you create stuff like stitches on clothing, tentacles, texture on a tree branch, wires, all sort of things that are currently not possible.
