How do I find out what NFTs are owned by people I follow?

The default view on NFT Collection Pages is a list of all the individual NFTs in a collection, which can be sorted in a bunch of different ways. 

Above the list of individual NFTs, there is a toggle that allows you to switch this default “Explore” view to the “Owners” view. The “Owners” tab lets you discover all of the NFT holders of a single collection, and this list can be further sorted to include only wallets you follow.
