all right, i will implement this,
but I mean to use sqllite or other database cache as with tiles and prefetching, and be able to retrieve polygons and points as custom layers in later sessions. i think it would be great, i am drawing polygon layers of many thousands and it takes long time to read from shapefile and render, so i thought about caching and retrieving, maybe you figure out another approach radioman, as you're the master here! what do you think?
thanks all the same
