Feature Request: "SteamOS Appearance" - Zorin-Style Layout Switcher, Native Workshop Live Wallpapers, KDE Connect & Legacy Storage Optimizations

To: SteamOS Development Team / Valve Corporation

As SteamOS expands beyond the Steam Deck onto desktop PCs and living room Steam Machines, Desktop Mode evolves from a utility background tool into a core pillar of the user experience. In a market where hardware components and upgrade costs remain high, the strength of SteamOS should lie in maximum software efficiency, flexibility, and user accessibility—whether on a 65" TV or a multi-monitor desk setup.

While KDE Plasma offers immense flexibility, customizing Desktop Mode currently requires technical manual tweaks and third-party plugins that frequently break following SteamOS atomic system updates.

To make SteamOS the ultimate all-in-one operating system, we propose a native Valve tool—SteamOS Appearance & Desktop Hub—along with core system optimizations:

1. One-Click Layout Switcher (ZorinOS Style)
   A simple native interface to instantly switch desktop paradigms:

Living Room / TV Mode (10-Foot UI Desktop): Features large icons, an enlarged taskbar, and scaled text designed for effortless controller navigation from the couch.

Windows Classic / 11 Layout: Traditional start menu and bottom taskbar layout for seamless user onboarding from Windows.

macOS / Dock Layout: Bottom dock with a clean top panel.

Compact / Handheld Layout: Tailored for smaller handheld screens.

2. Native Live Wallpaper Support (Steam Workshop Integration)
   The Issue: Wallpaper Engine is one of the top-selling applications on Steam, yet running live/animated wallpapers in SteamOS Desktop Mode relies on third-party KDE plugins that break after OS updates.

The Proposal: A native rendering engine baked into SteamOS/KDE Plasma that allows users to apply 2D/3D scenes, videos, and dynamic wallpapers directly from the Steam Workshop with one click, completely update-safe across atomic system upgrades.

3. Native KDE Connect Integration ("SteamOS Connect")
   Deeply integrate the power of KDE Connect into both Game Mode and Desktop Mode with zero manual firewall/pairing hassle:

Wireless File Transfer: One-tap transfer of ROMs, media, and files between smartphones/PCs and SteamOS storage over Wi-Fi.

Phone as a Couch Trackpad: Turn any smartphone screen into a remote trackpad and virtual keyboard for living room TV Desktop navigation.

Shared Clipboard: Instantly copy text, URLs, or activation codes on a phone/PC and paste directly into SteamOS.

4. Storage & Legacy Hardware Optimizations (SATA SSD Support)
   Maximizing performance without forcing users to buy new M.2 NVMe motherboards:

First-Class SATA SSD Support: Official installer support optimized for traditional SATA SSDs, HDDs, and SD cards.

Transparent File Compression (zstd on Btrfs): Real-time system-level file compression. Reduces game install sizes and drastically speeds up loading times on SATA SSDs, as modern CPUs decompress data faster than SATA bandwidth constraints.

Memory Management via zram: In-memory RAM compression to maintain smoothness on systems with lower physical RAM specifications.

5. Curated Software Hub & 1-Click System Restore
   SteamOS Software Hub: A streamlined Flatpak app store for 1-click installation of essential desktop software (Discord, Spotify, OBS, LibreOffice, EmuDeck) featuring Valve verification badges.

1-Click System Restore (Btrfs Snapshots): A dedicated "Rollback Desktop Settings" feature to easily undo desktop layout breakages caused by user tweaks.

No source files, tests, or entry points are identified. Begin by breaking the proposal into separately scoped features and confirming which SteamOS or KDE components are in scope. Done would require an agreed design, implementation plan, and acceptance criteria for each selected feature.
