this is kinda stupid but i would like to ask. You know how after a flight ends it shows the path, well maybe you could click on something and it will show the little plane go over the track again to show it as a mini clip kinda like the front page when you can see the all the flights in the air move. If you like this i have to say make it so its fast but not to fast. 
like i said kinda stupid.
Not sure how they could implement that, but it would be a great tool for debriefing after practice flights with IFR holding.
