Here are a few things I have been told that are not available but would love to see.
1... Type Array assigned directly to a dataset instead of adding 1 pushpin at a time.
2... The ability to set the visible property on a pushpin dataset
3... All the above to increase speed.
4... Ability to set the level of pushpin visibility
5... Reference ID for Pushpin so duplicate names can be used
Anyone want to add to this feel free ........
