I just posted my Riley Greene green mojo auto as a Mantelpiece, and maybe I wanna add some other cards of his like these, too. But at some point, that tab is gonna start to look kinda clunky and unorganized.

Can there be a way to allow users to (a) easily change the order of items they added as a Mantelpiece, or (b) move those items into some sort of subfolder, so that they can organize their collection by player (or by set, or team, or however else they'd like)?
