it doesn't really have a lot to do with viewing all your pokemon,i said there should be an option there or/and in "your team" so we can mark our pokemon as favorite also at if you have a lot of pokemon in your account,it takes a lot of time to load them,with a favorite filter you can see your fav pokes easily(iv'e tried it when you search a poke in an account with a lot of pokes,it lags a lot even though if you choose a certain category/filter it doesn't)
