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).
Description
Slider hell is a bit of an issue here when setting quantities
Alternatives
Instead of a updating text label please use linked text input fields for all quantity sliders for added precision
