could the sound triggers be moved from the items to the game engine? Or could Item classes (epics, legendarys, double rares, rare components) get at least an empty sound trigger. This would make it super easy for the community to add drop sounds by placing files into the /settings/ folder structure (like the lootsparkles) without the need of external programs or mods running.
While asking for this the only thing beside that would be an different lootsparkle trigger for double rares, which could trigger the same effect but renamed. So that those who wish can easily modify the vfx.
