Enforce the moving screen rules, I absolutely hate the plays where someone gets an open 3 because their center is setting a massive moving screen.
Also, goaltends should be automatically reviewed and corrected, either by New York or a video review ref in the arena. There's clear objective rules for goaltending, it's not something that should ever gets missed but refs miss it all the time. And on a similar note, add the possession arrow for 50/50 balls out of bounds. No need for a minutes-long review, just give it to someone and keep things moving.
