[Feature Request] Clear ground track(s)

[dl9sec]

I have about 20 sats in view. It sometimes happens, that i activate the ground track of a satellite, track it, doing some other stuff, listen, switch between sats and then loose the satellite i acivated the ground track of. In this case it could be realy hard to identify the sat, the ground track belongs to and it would be helpful to have a "Clear ground track(s)" feature to get a clean map again.
