While the current system controls are good, I just feel like the ability to rebind certain things, like the movement to something else, certain action buttons, etc, would be nice, along with some improvements to the general GUI... an example is this discussion page, in big picture mode, it's all the way on the left side of the screen, it looks unnatural, and should be centered... it just needs better polishing on certain screens like this. This isn't to mention the constant xbox controls all over the place "Y", "X", "Steam Button"... instead of what they are "Esc", "Space", "Enter". An option to switch those buttons to the keyboard ones somewhere in the settings would be nice.

Overall suggestion/ideas to add to Steam Big Picture mode:
- Rebinding capability for controls on the keyboard
- Polish the UI for certain pages in Big Picture
- Allow control icons to be switched to their PC counterparts in settings
