I have a business case where I would need to draw shapes on a MapView.
The primary need is polylines but polygons and circles would also be great to have.
Google Maps offers Polyline, polygons and circles and you can specify fill color, stroke color and width.
I'm afraid I have to look at another cross-platform solution but if Corona makes this possible I would use Corona without a doubt.
What are the plans for Corona SDK to improve MapView to something really useful that a lot of developers would benefit from?
