Since we don’t have taxiway diagrams, SID’s/ STARS this would be very helpful while controlling. I don’t know if fore flight is capable of showing multiple planes I’m sure it is as it has ADS-B capability, but this would help.
Nice idea, I’m surprised no one else has posted the idea before… :)
@DavidCutler is working on so something like this for controlling, albeit not using ForeFlight. He can tell you more.
