the idea is simple. often times I am creating a design, in witch two objects share a curve/edge, but have a different fill color. the only way to make the different fill color is to create two separate objects, but then later on if you have to edit the line you have to edit all instances of the object. or sometimes I have the same object that I want two different fill colors on, and again I have to make two separate objects. the same goes for strokes. so, I sujust that there be some way to within one object have totally different fills and strokes. there is already a way to have multiple fills, but they only layer on top of each other with different opacities, and same with strokes. I think that the different fills and things could be added using this same UI, witch would also allow the mixing of different fills as well. you could also apply / remove the different fills to different area using something similar to the new paint / bucket fill tool. anyways, I know this might be a bit challenging to code, but I really think it would be helpful and I can help if you want, but I don't know much. anyways, feel free to add on to this in the comments below!
