True. I also want to see the orbital lines of other objects nearby as you approach them. Seeing the orbital line of the planet still displayed as you approach a station is often helpful in lining up, especially when you approach from above or below. Just having the orbital line of the station when everything else is behind you doesn't work because a line is a line and viewed from any direction, is just a line. So you can't be sure if you are actually on the orbital plane or still above or below it. At present, the orbital line of the planet disappears when you get to a certain distance from it, leaving only the orbital line of the station.
With the absence of an entry vector for the stations, it's useful to bring us out at an angle up to 80 degrees from the mail slot. Personally, I'd prefer to have an entry vector we can follow to bring us out closer to a 30 degree cone from the mail slot which would also be more useful for smugglers who can't afford the luxury of flying around outside too long where they can be scanned. Since we don't have an Autopilot that can bring us out of SC right in front of the mail slot as we did in the original Elite, the entry vector would give us some way of doing the same thing manually (and gives us something to do in SC other than wait for a light to appear to tell us it's safe to drop out).
