Worldinfo is a mod that shows a brief name for any item or entity you aim at in Minecraft. It’s a handy little icon so you know exactly what you’re about to encounter or if you have no idea what sort of block you’re about to take.
It’s a simple mod with promise for future updates and more info added. It’s also a great tool if you’ve been away from Minecraft for a while and need to know what sort of new blocks or items may have been added. Instead of leaving the game you can see that info right at the top of your screen!
