Feature: Xbox Controller Support

### What's the Problem?

I'm on sofa and want to open a file (a movie, or music folder, or whatever) without moving to pc, I have to use either wireless mouse or keyboard. But I only have controller in my hand.

While the current Files actually respond to my controller, however somehow confirm button (A) doesn't really work, and after using the context menu to get into a folder, the controller focus is somehow gone forever.

### Solution/Idea

Add controller support.

### Alternatives

wireless mouse/keyboard, or remote access through cellphone. But the mouse cursor on big screen is not as good as controller.

### Priorities

| Capability | Priority |
| :---------- | :------- |
