NomNom is the most complete savegame editor for NMS but also shows additional information around the data you're about to change. You can also easily look up each item individually to examine its attributes, independently of a savegame, or get other useful information that are not related to a specific savegame (but enhanced if one is loaded).
Can you update save editor to newest version of the game? This is very good tool that speeds up progress. Please don't waste potential of it...
