This is an addon for Thaumcraft Mod. Thaumcraft Node Tracker allows you to automatically keep track of nodes you have scanned with the Thaumometer. If you have already scanned the node, it will update the list with any changes in the node. This is a CLIENT SIDE only mod.
If you are wearing the Goggles of Revealing you can also select the node and get an in game arrow pointing you in the nodes direction.
