My suggestion is that when you have multiple plots next to each other that a single person owns then the path between them should be removed and replaced with plot. This is so when you have 2 or more plots next to each other and you are building something big, then you don't have to worry about how much space you have until you get to the next plot where you will have to start adjusting things. I hope that makes sense. I realize that this may cause a lot of lag but you all are geniuses. I also think that this would come in handy for roleplays, you wont have to add people to your multitude of plots and it will just be a lot easier on the player.
