I'm working on an End of Round Report. It's pretty basic (it's just a fancy textbox with TML formatting), but it should work nicely. Gamemodes will be able to inject custom fields and data.
Here's an example of the API as it is right now:
Slayer_Scores.initList("200,300,400,500","<h3>Player\tScore\tKills\tDeaths\tCaptures</h3>"); //tab breaks, headings
Slayer_Scores.addLine("<colorHex:ff0000><b>Greek2me</b>\t150\t51\t47\t2</color>");
Slayer_Scores.addLine("<colorHex:0000ff><b>Mouse</b>\t15\t16\t32\t0</color>");
