Heh, I use the ADC of EVERY SINGLE ship I own. I'm lazy. It's not that I can't dock, I've done it thousands of times, I just don't like doing it any more. I'll use Limpets to collect things too. I did it thousands of times manually before Limpets were a thing. Ain't going back lol.
Re: the PiP thing, I actually noticed that too. I mean, the DC's would previously pop pips to engines while manoeuvring outside, and pop pips to shields when passing through the letter box. That was wise as the DC would regularly bump. Can't recall the last time it did that though, even though I've been flying a heavily laden Cutter most recently. I did notice that my Cutter always passes out of the letter box at 25m/s now, so I get an immediate trespass warning message the instant I take back control to accelerate away.
