Shapes: Vector Drawing Tool

I'm pleasantly surprised and I feel like this could work up to being an extremely useful art tool. I really like the repeat tools, it's a something new other vector creaters in the app store do not have. But it's lacking ALOT of basic tools for a art app. There's no undo button, there doesn't seem to be a way to use filters or really any vector manipulation functions, so you're stuck with solid primitive shapes for now. I would absolutely love to see a draw feature in the future.
