Sorry if this is an extraordinarily dumb question, but does not work anymore to give you another layer? I remember a few years back before I went on hiatus it still did! Did they remove its function because they changed the layers to items total and not per layer anymore?

Yep, all of your assumptions are correct :)

aw, that sucks, but thanks for letting me know! (And sorry for such a late reply haha, I haven't been on in a bit!) <3
