The Xbox One Elite controller is Microsoft’s ultimate controller and by using the Xbox One Accessories app, you can remap buttons, set trigger and thumbstick sensitivity, and control a whole host of other options. Some of that level of customisation is now available to all controllers.
The Accessories app can be launched directly via the app, or by going to the settings menu and choosing ease of access or the device and accessories menu. After launching the app, you can remap the face buttons of a standard controller but all other customisation options are only available to Xbox One Elite controller owners. There’s also only one profile save available making customising your standard controller a rather lacklustre affair.
