WorldInfo displays information about the world around you on your HUD.
Currently there is support for only Blocks and Entities, and mods can add their own handlers as well.
Note:
WorldInfo is a mod for the Rift Modloader and needs Rift to work, not Forge!
1.13.2 versions require Chocohead's fork of Rift!
