It'd be super neat if, when submitting a run with a video, you could also put in what time in the video your timer started at, and then anyone viewing the board could select multiple runs and get a viewsync link made up to watch the runs race-style. See how close they all were or whatnot, i.e. https://viewsync.net/watch?v=zxuPMQD5Zdw&t=3.1&v=HEsfOwvpKmQ&t=0&v=mButm-65Ic0&t=0.19&v=4m9f9A7pOhk&t=2.7

The only downside is that they only support YouTube, so you can't have Twitch videos synced with YouTube ones.
