With the action button seemingly coming to iPhones and already on the Ultra if you like ugly watches, why can't the useless side button on the normal Apple Watch be given the same treatment? I double tap it a lot for Apple Pay but the single tap is useless - takes you to apps. You press the crown and get the to almost the exact same thing. Would be great if you could customise it - for example I'd use it every morning and night if you could assign it to cinema mode.
