I discussed this with Walter and we had some great ideas. Could drive the smaller Traffic Radar size to have the Touch to Expand, much like the Vertical profile instrument. Then the larger pop up would allow for touch and view details on a particular target.
It would also fairly simple to Auto-Pop the Large Radar if inside the Range or if Yellow or Red Alert status. Obviously, this would be an options to Auto Show Radar or Disable or Active Indicator.
There are some UI challenges, like must have a Dismiss or Hide and a way to change the setting. All very simple, just finding the best intuitive placement. But then this is what Walter and Brian do best. Stay tuned.
