diskOS Disco! 1.5.0

Boomshine is built in, and any app can join the navigation circle.

Boomshine

A chain-reaction game for the round screen. Dots drift around; tap once to set off a blast, and every dot it
catches bursts too. Catch enough to clear the level, across twenty levels. Two looks: NeoN (bright rings on
black) and Pop! (soft pastels on deep blue).

• Built in, nothing to install. Add Boomshine in Disco Options > Disco Menu, or open it from All apps or a
  Shortcut.
• Your music keeps playing; the game is silent.
• Best score and level are saved. Scores from the earlier separate Boomshine app are carried over.
• Hold Volume Up for 3 seconds to close it if it ever stops responding.

How to play

Apps in the navigation circle

• Any installed app (Disc Shelf, future apps) can now be added to the navigation circle in Disco Options >
  Disco Menu, next to the built-in sections. Entries keep their place as you install or remove other apps.
• Landing pages. Choosing Boomshine or an app in the circle shows its landing page first: a picture, a short
  description and one button. Nothing launches until you tap it, so browsing the circle is always safe.
• Apps without their own page get a tidy default ("Installed app" and Launch). App makers can set the line,
  description and button text in app.conf (details).
• Folders without anything to run are no longer listed, and Album Roulette and Boomshine never show up twice.

Disc Shelf

• Updated app.conf with a landing page ("Your Navidrome, on the card.").
  Reinstall it to get it; the app itself is unchanged (1.0.4).
• A fuller guide: what you need, every setting in shelf.conf, troubleshooting, going back and removing it.

Install

• SD update: download mq_ui from the latest release,
  sign it with your keys and install it from the card (guide).
• Disc Shelf 1.0.4 and Album Roulette 1.3.1 are unchanged and installed separately.
