with all the living story updates my bank is starting to get full with all the free stuff that the living story meta-achievements have produced, such as wings, investigation kits, mini sanctum models etc etc. my suggestion is to have a drop down menu in the hero ui so that the skins can be a permanant unlock (such as the achievement skins) so i dont have to have a copy cluttering precious space, and whenever i choose to apply a skin i can get a copy from the hero window.
just throwing the idea out there
