v0.4.0

v0.4.0

Released 25 July 2026

The Steam Deck app grows up. It now looks like the rest of SaveLocker, sounds like the rest of Game
Mode, and carries the same information the desktop agent UI does.

On Steam Deck, download the newer tarball and re-run install.sh. Windows agents update themselves.

New

• The Game Mode app has been redesigned. Same palette and typography as the web console and the
  desktop agent — no longer a bare debug panel. A header with connection status, a left rail of
  destinations, and a proper 1280×800 layout that actually uses the Deck's screen.

  • Overview leads with the numbers that matter — games tracked, saves backed up, last sync —
    then your tracked games and this device's details.
  • Settings is new here: change the sync settle delay, toggle start-on-boot, and remove games
    from this device. Connection details are shown read-only, since Game Mode has no keyboard.
  • A gamepad hint bar shows what A, B and the D-pad do on the current screen.

• Interface sounds. Navigation and selection now make a sound. Where SteamOS's own Game Mode
  sounds are present they are used, so the app sounds like the rest of the console; otherwise
  SaveLocker generates its own. Turn them off in Settings → Interface.

• Conflict warnings now reach the Deck. If you launch a game another machine has checked out,
  the warning appears in the Game Mode app.

Fixed

• Save-conflict warnings were never shown on Linux at all. The Steam launch wrapper detected the
  conflict and then discarded it: it is a separate, short-lived process from the sync daemon, so the
  warning had nowhere to go and only reached a log file that Game Mode never displays. A Deck user
  who launched a game another machine had checked out was simply never told. Warnings are now stored
  on disk, so both the Game Mode app and the browser UI show them, they survive a restart, and
  dismissing one dismisses it everywhere. They expire after 24 hours.

• D-pad navigation in the Game Mode app. Moving between the menu and the page content required
  pressing A to enter a pane and B to leave it, and the selection highlight was so faint as to be
  invisible. Now: the D-pad moves straight between the menu and the content, Right jumps to the
  first control on the page, and the cursor is clearly outlined wherever it is.

• The discovered-games list was unreachable after a scan. Pressing Down from Scan for games
  jumped back to the menu instead of moving into the results, so there was no way to tick a game or
  reach Enroll selected.

• The footer could be selected, and doing so scrolled its own contents out of view.

• Long save paths ran off the edge of the screen. They are now shortened in the middle, keeping
  the part that identifies the game.

Known issues

• Pressing Left does not always return to the menu. It works from Overview; from other screens
  you may need B instead. This is a limitation in the UI toolkit's gamepad navigation rather
  than a simple bug — see Backlog.md.
