I would love to have the ability to add yield lines on my taxiways.
In this image of my airport, you can see how arrivals and departures are immediately separated to avoid traffic jams. But, they converge on one communal taxiway by the gates. It seems like, currently, arrivals have priority over flights that need pushed back even if they are miles away. I dislike this because if a flight gets delayed, it can’t push back until all arriving flights have cleared the taxiway behind it, and this risks delaying the next flight on the stand. A yield line would solve all these problems so that arriving aircraft can make their way all the way up to the shared taxiway, while letting departures have priority to clear the stand for the next plane.
