Dynamics>Angle set - None helped - brush is now in center.
I just had to go to finger dynamics - and set Angle to 'Stroke direction' - for brush alpha to follow the pen azimuth (I'm not sure if this is bug, that finger properties are affecting pen props).
But still offset feature is great, imo it could be reduced.  In Infinite Painter  offset value can be set by user. Positive values move brush away from pencil (good for aerograph like effect), negative is moving alpha toward pencil center (pencils).
I measured how much more offset is applied in AStudio Pro compared to  IPainter:

So even with max offset value, Artstudio is moving brush alpha around 50%  more compared to IPainter (and usually pencils in IPainter are not set to max offset).
I hope you will consider reducing offset, or adding slider for it.

Great update 2.2 congrats.
I wish for new option for Aux color - auto pick from initial pen position.
Basically it would pick color under stroke, before first brus dab is applied, so that we could blend with background color under cursor.
Right now if I have red background, and paint with yellow, aux color would blend to default wite color.
With this new option aux color would be automatically set to red, so that  I could blend with it.
BTW. you have the worst captchas in this forum in the world
