What changes for the player?

Tapping Alt opens a quick menu that looks and works like OMSI 2's: a 5x3 grid of large square icon tiles in OMSI 2's order, the chosen tile's name under the grid, and an arrow at the bottom right for the next page. Lit tiles (route arrows on, a tour being driven) are orange as in OMSI 2, and tiles that cannot be used right now are greyed. The menu also works from the keyboard.

How to test

Any map and bus. Tap Alt:

• Page 1 holds place / change / remove / reset vehicle, city map, timetable, destination, repair, refuel, wash, route arrows, time, weather, controls and statistics. Each tile does what it did before; Time and Weather open their own tabs of the world options.
• Hover a tile: it is chosen and its name is shown under the grid.
• Arrow keys move the choice (past the left or right edge onto the other page), Enter starts the tile, Tab / Page Up / Page Down turn the page, Alt or Esc closes.
• The › arrow (or Tab) shows page 2: camera, vehicle and world options, options, back to my bus, save, save to a slot, screenshot, photo mode, skip the next stop, end the tour, player list, administration. Tiles the pause menu does not offer right now (skip stop without a tour, multiplayer ones offline, back to my bus while seated) are greyed and do nothing.
• Turn the route arrows on: their tile turns orange. Start a tour: the timetable tile turns orange.

Screenshots

What does this change, and why?

• Kind::Tile gets focus and off; a tile with no text is drawn as a square of its icon alone (omsi-plugin-ui/src/square.rs), with an accent ring when focused and greyed when off. Tiles are only built by the game, not by Lua plugins.
• quick_menu.rs keeps the page and the chosen tile, builds the grid and the footer, and handles the keys (game_panel_key) and the hover (from the hit under the cursor, only when the cursor moves, so the keyboard choice is kept while the mouse is still).
• The pause menu's line actions move out of menu_choose into game_menu_action(id) (unchanged otherwise), so the page-2 tiles run exactly the pause menu's code. Which tiles are greyed comes from game_menu_items().

What could break?

While the quick menu is open, the arrow keys, Enter, Tab and Page Up/Down go to the menu, not to the bus. The pause menu's lines now go through game_menu_action; its behaviour is unchanged (load, quit and plugin lines stay in menu_choose). Not tested in VR (the menu is not shown there) or on a server.

Performance

No feature with a runtime cost: the panel is laid out again only when it changes (page, choice, lit or greyed tiles).

Checklist

• cargo test --workspace and cargo build --release pass (tested: omsi-app, omsi-plugin, omsi-plugin-ui tests and the Windows release build)
• The pull request contains a single change
• Before/after screenshots are in the description if anything changes on screen
• A new feature has its performance table filled in
• New or changed interface texts are in crates/omsi-app/locales/app.yml, in every language I can (only existing texts are used)
• Online play, saves, settings and mods made for the previous release still work, or the description says what changes
• No original OMSI 2 content and no file of a megabyte or more in the commits

• Unpack the download into a new folder, not over your openOMSI. The launcher shows the version as ...-pr3335, and a test build is never updated. It shares your settings and OMSI 2 folder; mods you installed into your openOMSI folder are only seen when you unpack it into a copy of that folder.
• Android: the download holds an APK that installs as a separate app, openOMSI PR feat: the Alt quick menu as OMSI 2's grid of icon tiles, with pages and keys #3335, beside the release, and shares its openOMSI folder.
• What to try is under How to test in the description. Please comment with what you found and the version the launcher shows.
• The links work for 14 days after the build.

Looks good: the pause menu's actions move into game_menu_action unchanged, greyed tiles take no clicks on mouse or keyboard, the key handling and paging are covered by tests, CI green. Thanks!
