This is a major thing that might work. Recently people have been getting upset at the ammount of people going the same routes so. There should be a way to turn of flight plan copying on your flight plan. But if you copied someone else’s you can’t turn it off. But you could also make it so only sertan people can copy your flight plan.
I’m 50/50 for this. If someone copies your flight plan, then technically you should be happy because the only reason they’d copy it, is if it’s good. But as what @IceBlue said…
The option to turn it off is completely useless. The people that are currently copying flight plans are going to continue doing that. Then the people that currently don’t copy others’ flight plans will use the feature and turn the function off. In the end, it won’t make a bit of difference because people will continue what they were previously doing. Plus, you can’t just make a button go away like that. It’s either there or it isn’t.
