Great adiction, it is exactly as you mentioned: "If coinmarketcap.com wasn't awesome enough, it is about to get better!". Not only it is the most used, but it is always working on something to improve and keep the site appealing to everybody.
Great addition, especially if we want the masses and less informed people to get into crypto, this will help a lot.
It will help keep them from buying dead projects hoping to catch the next bitcoin.
