Are there any plans to add tooltip support for individual TrackPoints in a Track Layer? Any comments on whether it would be a good idea to use an Icon Layer instead to gain tooltip functionality? I am typically displaying around 1000 points at a time, so performance may be an issue.

Alternatively, I may look into adding tooltip support for TrackPoints, but I'm not sure what level of effort that will be.

Thanks!

Track points will be undergoing rework soon, for both performance and appearance, so this is maybe not the best point to invest a lot of effort into them. But I think a likely way to handle tool tips for them would be to make each point pickable -- a requirement no matter what -- and have the app listen for the event and display the tip, either itself or with wwj text rendering. Memory usage will likely become an issue if each track point holds tooltip text. Icons currently hold tool tip text, and that's probably not the best way to do it. We had a deadline to meet.
