Ability to cover on top of outlines
A brush that marks over the original pictures lines. For example: if you are in freehand and have a yellow line and it goes over the line of the picture it doesn’t get interrupted with the black line.
Now that we can change line color (yay! thank you!), we need to be able to color completely over them so pictures with pupils can have other-than-black lines but still have black pupils. Otherwise things have crazy eyes.

An option for advanced free hand coloring that would color over the top of lines would be amazing.
