Feature idea: Big Picture style controller mode

[pqzmggg]

Summary

A dedicated full-screen, controller-first mode for GameNative, similar in spirit to Steam Big Picture: browse, install, configure and launch games without ever touching the screen.

Motivation

Many people run GameNative on handhelds, foldables, phones with clip-on controllers, or hooked up to a TV / external display. The recent controller focus work (favorites toggle on the west button, action bar hints, focus rings on the store pages) is a great start, but parts of the app still assume touch. A single, consistent couch/handheld mode would remove that friction.

Proposed UX

Entry

• Toggle in the main menu
• Setting: "Start in Big Picture mode" and/or "Auto-switch when a controller or external display is connected"

Home

• Horizontal shelves: Continue Playing → Favorites → Installed → Steam / Epic / GOG / Amazon
• Focused game's hero art as a blurred backdrop
• Large cover tiles with clear focus highlight

Game page

• Play / Install / Update as the default-focused button
• Download progress, size, cloud save sync status
• Compatibility info for the device
• Shortcut into container settings (driver, DXVK/VKD3D, env vars), all navigable by D-pad

Settings & text input

• Controller-navigable settings screens
• Gamepad on-screen keyboard for search, env vars, launch args

In-game

• Guide/Home button opens an overlay: Resume, Return to library, Exit game, Toggle HUD, Quick settings

Suggested button layout

Button	Action
A (South)	Select / Launch
B (East)	Back
X (West)	Favorite (keeps current behavior)
Y (North)	Search
L1 / R1	Switch tabs / shelves
L2 / R2	Jump page
Start	Main menu
Select / View	Downloads queue

A persistent bottom bar would show the hints for the current screen.

Nice to have

• Optional navigation sounds and haptics
• Landscape-optimized layout that also scales for TV output
• Remember last focused item when returning from a game
