Since I didn't find one in the forums, I made a leaderboard with important balance-related information such as each players' resources, unit count, resources in units, etc to use on my test maps, and I'm just releasing it here. It should support any number of players (change the maxplayers variable), but I've only tested it with 2 players. It's pretty crude, I only put like half an hour into it, but it gets the job done.
It's plug and play. Import it into your map's triggers and the leaderboard will show up. Use/modify freely, with or without credit.
