We all know that this sim has a steppy learning curve and that new players need even more than a week to be useful. The problem is that we dont know who is still learning and who is not. Sometimes you are giving some clear instructions to somebody and has no response, no reaction, even if these instructions are mandatory to survive. Sometimes you are asking for help to a nearby player and again, no response, no reaction. Some veterans explode with these players ignoring that they could be new ones still learning to take off.
To solve that, I propose a new setup option to enable the "new player" flag. If enabled, and "L" of learning will be shown with the player name in the plane icon.
