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
