This is a good question, similar to mine which was being able to see live where the traffic was coming from. When looking at the traffic page when flying we are presented with a big list of the traffic and their respective distances etc. To analyse where that traffic is coming from, PAW antenna, 1090, ATOM, iGrid, it would be great to have an additional column with the 'source' listed. My recent efforts to find the performance of my newly located antenna was made difficult as I didn't know where a particular contact was derived, so I didn't know what was actually picking the traffic up. I ended up with everything but the 1090 disconnected, disabled so I could see how that was performing, the column I'm suggesting would mean it was easy to see that information live at any time.
Maybe not possible........
