There also seems to be a duplication glitch when loading saves onto the editor usually some and in rare cases most of the mods/item list repeats several times..
I was also wondering if in future versions you plan on separating the mods per weapon/armor type in different lists? That would be cool.
Not sure what the "duplication glitch" is that you're referring to.
I like this second idea though, there could be Weapon Mods -> Axes, Weapon Mods -> Swords, Weapon Mods -> Generic, etc.
