Well, for a smooth line you always need to anti-alias -- that's what you get with a blurry border . For the texturing feature, I'm working on that right now. Not sure whether it will have the features of photoshop, but it can do some things. I haven't started on the dual brush feature yet -- not sure what that is used for

Dual brush allow to make more random in the brush for example you can have the first brush who is a square and and the other who is a round brush and with the rand om of the second brush you can do a gruyere brush with random hole in it.
I admit this is not the best example
usualy i use it to create hole or randomise the border of the brush. But i use it rarely i confess so this is not the most important stuff.
