The issue with .abr files is that it is a closed, undocumented, binary format, so there is no way for us to decode it in Painter for now unfortunately.
Scattering should already be there through the Position Jittering, even though it's not as advanced as the PS scatter. Color jittering is coming soon. The rest will eventually come at some point, so yeah, we got a lot on our plates on the brush side
