Describe the Suggestion

I like putting my signal as close as possible to an intersection, but each time I'm one too far. It would be great to know exactly where the rail branch off like in the pic

I didn't get what you meant by this, but maybe putting rail in buildmode in your left hand will help? It still displays hologram of the rail while when you left-click you place/use block in your right hand.

I mean, I want to see where the curved rail end to put my signal as close as possible to the intersection.
But I noticed you can see it with F3. Then maybe it would be better to make the intersection nodes visible without F3?
