We've all been there - trying to build something, running two Minecraft windows and switching between them while building.
Alt-tab no more! Schematica loads a schematic file and renders a detailed ghost image of it ingame.
It works flawlessly for 1.7.2 on Forge.

More info.
Suppose you did something in singleplayer that you want to replicate in multiplayer. With this plugin, you can put in a ghost schematic so that you can see what you're building!
