Here is an example of using wait in my app...

It seems to work better if I first load the map, then add markers from my database, rather than doing both at once.

There is not a good trigger to detect when the map is fully loaded and displayed.

So, I set an event listener for the page load, to trigger loading the markers from my server. Page load catches the process about halfway through-the map tile images are still loading from Bing.

I added a wait command in LC at this point, to give the widget a bit more time to process the map tile images.

Sometimes, webglearth JavaScript can get hung up if the data connection is slow. So, at the end of the wait period, I have LC trigger a moveback() function to nudge the widget and get the widget to keep loading tiles.

Wait helped because of imperfections in code outside of my control.

I also think wait can be useful inside of a loop that animates a movement, where you want to slow it down. However, this could easily be overcome with send-in-time handlers.
