Carrying cases should probably go under "swag - carrying cases" (renaming "swag" was discussed in another thread, if we settle on something it could be changed at the same time
)
I think most of the accessories fit in one swag subcategory.
As for Toys to Life, I remember someone asking about it in a thread since amiibo cards aren't figures; if the general concensus is to keep interactive figures though, I see no point in changing that
