I have over 200 marketplace items, many of which I don't use anymore. That clutter makes it difficult to find the specific items I want in the Art Library tab. I propose an option be added to the My Marketplace Items page to disable specific packs. It'd be easiest to disable them account-wide, but the ability to disable/enable them for specific games would not be unwelcome. Once disabled, a marketplace item would not appear in the Art Library tab in-game, eliminating a lot of clutter. When a user was ready to bring an item out of retirement they could go back to the My Marketplace Items page and re-enable it. I would expect this to be an obvious quality-of-life improvement, because the clutter keeps me from buying more market place items all the time.
