I was thinking it might be nice to be able to edit plots that have been submitted, even if they've passed, so that you can continue to improve it and implement the feedback received, and maybe fix any derps you realized you made after you already submitted it. Obviously as it already passed you can't submit if for review again, but it would be nice to have that satisfaction of being able to bring your plot past the passing score. And if you made any derps, you would be able to fix them and not have them preserved forever for all who fly by to see. So yeah, I'd like plots be able to be edited after the review score is given, although you still wouldn't be able to edit them while the plot is being reviewed.
