How would you like the feature to work?
Id like to have some control over what exactly is "modify" when I sell my clothing (or any other creation). At the moment modify practically grants almost full control over the object. Id love to be able to set exactly WHAT is modifiable on my creations when I sell them. For example I sell my fatpacks as MOD, but really I only want people to be able to modify the texture colors and transparency. However they can actually delete scripts too. Id like to lock down the actual texture, the normal and the spec maps but still allow color changing. And lock down the contents tab. These could all be separate options.
Why is this feature important to you? How would it benefit the community?
Having various states of "modify" permissions would allow better control over the things we make. People could still make full mod items but for those of us who wish to keep some things locked down (textures, contents of the item etc) we can still let customers modify some parts but not others.
