I found a small problem with this:
When a planet gets colonized or a shipyard gets made and it sees if there is a shipyard nearby that would be in the green zone (no penalty), planet automatically becomes a sponsor.
It works perfectly under normal conditions. I found a star system with 3 planets to colonize. I managed to colonize all 3 before the shipyard was built. When it was built, all 3 were automatically connected to it. Before this change I had to remember, maybe too many turns later, to manually connect the other planets to the shipyard. Very irritating. This way is much better and much appreciated.
The small problem was in another star system where I colonized one of the 2 planets and built a shipyard for it. The other planet required extreme colonization, which I didn't have. Another race eventually colonized it despite my strong influence in the system. A number of turns later the planet flipped to me.
The small problem was that it didn't automatically connect to the shipyard. I waited two more turns to see if it took a turn or two, but it never connected. It was definitely in the green zone.
It would be nice if whatever was done to make colonized planets automatically connect could be done for flipped planets.
I like all the other changes also. I'm having to adjust to the planet build queue being moved and space rockets being moved, but I am adjusting. I prefer the way they are over the way they were.
