Yes! I love the simplicity and style of the map generator. Moreover, I think its utility across various media is massive. I'm sure I am not the only person so far to see it as a board game design tool if not yet as a full blown board game design app.
I agree that variable shaped polygons would be a challenge to automate though something could be done similar to the way shapes are manipulated in Powerpoint, PS, Illustrator, etc. The ability to align and link points, then create the next polygon from there as opposed to creating the polygon and then aligning would be nice, however, lets set that aside for now.
Hexes, simple grids and brick pattern grids via vector art would be much easier as a layer overlay and again, with the ability to scale them either vertex to vertex or face to face. Example hex scale: 500 yd/hex face to face. Compass orientation of the grid would be by the vertexes.
