Make it easier to update PFP.#79

Right now we have to scroll through all our NFTs to find the one we want to use as our LooksRare PFP and that takes a ton of time for users with many NFTs in their wallet. And many simply don’t load due to the data crush. When I do it it starts with all my ENS names which makes no sense and since I have 60 of them in one wallet and 200 of them in another, that’s just way more wasted time scrolling through all those. It would be much, much easier if you allowed us to choose from a collection first and then scroll to the item we want to use or, even better, add a “set as PFP” link to each of our NFTs in the “My Items” page. I’m really hoping some major progress is being made behind the scenes on better user controls of our profile pages. It is, after all, the first thing people see whan they visit our page links we share in socials.
