The savegame editor has options to change required level, rarity and few other things like amount for items. But no stats. It also does not work on definitive edition savegames. The trainer still has the GM option but people said it's no longer working like at the beginning, i.e. its heavily limited.
So in both cases you shouldn't expect a full featured inventory editor like the inbuilt GM mode was until it got fixed/broken by a game update.
Okay sounds good.
Do you know if at some point the GM editor, and save editor will be updated to work with DE?
