I was just going through my characters to clean out their inventories, which has become quite a task since they all have at least 10-20 stacks of transmute gems, but I also noticed as I was going through each character that over the course of the past few events, I have several pieces of bound event furniture pieces that I don't want to use. I then went to go to one of my "storehouses" to unload the furniture pieces when I realized that my main storehouse is at capacity.
It was then that I realized that we really should have a stickerbook for furniture/housing pieces - or at minimum, those limited time furniture pieces that are bound and that you aren't able to sell. Not only would that be a helpful way to manage these items, but it is much easier to go through your stickerbook to find the item you want and to recreate it than it would be to dig through my storehouse.
I could also see some propensity here to expand the furniture market if the stickerbook applied to every non-achievement related furniture piece. You can learn how to make a furniture piece by obtaining the blueprint OR by buying the furniture piece and deconstructing it (similar to deconning armor/weapon pieces). That might lower the demand for blueprints, but it would also increase the demand for furniture pieces themselves.
Lastly, if reconstructing them came at a cost of transmute gems (even a minimal cost of 5-10 gems), it would also help some of us with the overwhelming surplus of gems we have, and give us more incentive to decorate our houses (I have been slacking in this regard).
Anyway, just a random thought to further improve inventory management in this game, which is abysmal.
