Someone asked in Darkosto's chat earlier if prestige points could be tracked/displayed on the vanilla scoreboards. Doesn't seem like that's a thing, but it sounds like a pretty good idea to me if there was scoreboard support for that.

TL;DR: Add support to track prestige points via vanilla scoreboards.

I am currently working on a mod that adds scoreboard support, I am not promising that it will be completed or that it will be for public download.
