TLDR: I really wish there were better storage solutions.
I'd imagine a housing object for both of them, something similar to the Misc. Bucket, but I could also see it showing you all the possible papers/keys there are and how many you have of each.
I personally like to collect scrolls of every place, so I have a lot of storage occupied by scrolls. For the keys, however, there are so many of them, and some of them even have fragments. I personally fill almost 1 bank pages.
I could potentially see similar ideas of housing objects or just things similar to the emerald pouch with other of this game's mechanics, however, I feel like bounding them to the house would make them less op.
Other suggestions are, but not limited to: Ingredient Stash, Potion Brewery and Crafting Material Silo. I could see them working in some specific ways, and I believe these could help organize some of our banks.
I've seen the scroll pouch forum post, so whether it is needed was discussed there already.
I know not every player feels the need to have these, but for the hoarders out there, these things are actually awesome.
