Im still in the search for a better go-to Statistics plugin, my Stats3 is unstable, I cant convert to Statz and reading the recent reviews of Statz it doesn't look like it works properly at all.
Searching Spigot I found that the plugin "Content Management Interface" can display in-game stats! I assume this is pulled from the worlds stats folder and displayed in-game.
