Holy Megalodon Batman.
I was thinking maybe add a small svg program to FZ, like all you really need is square and circles and slight variations of those, but I read further and it seam you want FritzScape. Fritz coding would be hard, but Ink would be an order of magnitude worse.
Yeah I know about Ink's rudeness when I started trying to work stuff out 14 months ago. I was converting a PDF drawing to svg and the guy kept saying, "just Ungroup it, can't you read the bottom notifications" in an abrupt way. I did it and it didn't work, and he got more snotty. Eventually I figured out you have to Ungroup it many times, until it reads No More Groups. So I told him he didn't say to Ungroup it until it's at it's base, and then he was ok after that. Now that I have a few more posts on Ink they are ok, but even then you kind-of have to know how to manipulate people by the wording to get them to do what you want.
