So I've added an ArcGIS reference layer to my map visual. As I zoom around on the map it clears those features and re-draws them, which can take a while. Fair enough, I understand that's some complex computation going on.
My problem is there's no visual indication of what is happening, besides the reference layer features disappearing and then appearing one-by-one. How do we know when they have been completed loaded?
I think it would be better to set the "spinner" (animated bars at the bottom left) going until the reference layer redrawing has completed.
