i like it, xcept ID should show only in team. So that way it isnt easy for enemy to spot planes.
Also it helps the teammates know which plane is whos, giving the gameplay more tactical immersion.
So players that actually help scout yet gain no exp can at least be known for their cooperation.

perhaps ID only on the SQ leader and have the flight number as is right now.

Either that or since most GB only max out 4 per team, CV mode max at 10 per team, and AW generally have less than a dozen per team, a numbering scheme can be applied.

most of the time you can tell which plane came from which cv from their model and nationality. I mean those mustangs are obv from the tico and not the GZ or ryujo.
