The volume and sales of NFTs is directly correlated with the accessibility and interpretability of NFT listings and their value. By allowing collection owners the ability to display particular attributes of NFT listings, it would make for a far more seamless user experience, allowing users to find what they're looking for with more ease. The system would work exactly as custom filters work. Collection owners would be able to select a schema, select the attribute they would like displayed & give it a name. For string based attributes, such as rarities or names, the current custom filters work great. However, that system is ill fitted for varying numerical attributes. For my collection, Terraformers, the mining power of lands is the primary attribute that decides the value of lands & currently, users have to hover over each land listing, one at a time, to perceive it's worth. I've attached a mockup of this proposed implementation below. Thanks for your time, on a t break
