I think it would be cool if you could type in just @[username] and not user:[username] if you wanna see the saves of an user. It would be also cool if you could type in @[username],@[username] to see the works of TWO users. You'd see the saves on the first user you typed in on the first page(s) of the search results and the saves of the other user after the saves of the first user. I think it could be possible to search the saves of at most five or ten users.
