Doesn't this housing preview just preview everything? It doesn't check every item you've previously ever owned, I think. To have a glamour log of every single item you've owned would take a lot more info. Though I still think it's worth doing some how (WoW has nearly every item tracked account wide for example).

I had thought they might perhaps utalize on a grander scale a system they've used before in FFXI with set storage, but rather you collect a number of items from a content and then you've unlocked that whole content for glamour. In that way logging 30 items becomes more like logging 1. All the weapons and armor turn into "eeeyy you unlocked the vault, gj - all that glamour is yours now". Pros and cons obviously.. I tried to write more about that here (the Crystal Forge / Library).
