More logical orbit toggling for satellites

[Atque]

Currently, we need to search for the satellite in Satellites Configuration -> Satellites and check orbit to visualize its orbit, an unnecessary tiresome way. It would make a lot more sense if the orbit was automatically selected once the satellite was selected in the sky (via mouse click).

Bonus: It would make sense to automatically calculate one revolution of the satellite, instead of fiddling with segments. At least, that should be toggleable.
