Hi Pierre, I would like to work on more 2D illustration type tools for MoI in the future, but there are still a lot of very basic things in that area to work on first, like just having a concept of fill and stroke properties to start with. The space fill type function that is shown there is a lot more complicated than that basic stuff and I would think it would take a long time to develop so it would probably be quite a ways down the road before that could happen.... So I'm sorry but that stuff in particular is quite unlikely to happen for v4.
