Including a few simple sliders from the desktop version would make the mobile version extremely more useful.

Vitae has an aspect ratio slider for the oil brush, but that is useless since you can't set the rotation of the brush. The only reason to change the aspect ratio is if you can also control rotation. But that is missing. The other tool that desperately needs a rotation setting is the pallet knife.

Next, please add a stiffness slider to the oil brush. It is impossible to make a brush that creates multiple thin whispy lines (like for painting grass) without changing to a high stiffness.

Thank you,
