This Client Side add-on to Thaumcraft 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.
An in game list allows you to see nodes you have scanned and sorts them by Aspect (Primal Only) and distance from player.
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.
