In X3 Console View it's currently way too easy to hide a track but not so easy to re-show it. In Track View you can ctrl+H and shift+H to do this.
How often do you right-click to narrow a track in CV only to accidently hit the Hide Track select instead, because they are so close? Then you have to remember what to do to re-show it, which takes time and your mind off what you were just doing.
I don't know the best way to do it but I'd like to see something like a global "Show All Tracks" button somewhere.
