Welcome

regan.exe is a retro-styled desktop for Regan’s photos. On startup the wallpaper is a random cat picture from the gallery. The main area is your wallpaper: pick a still image or run a slideshow (up to 10 pictures) with smooth crossfades.

File Explorer

• Open File Explorer from the desktop or File → Open File Explorer.
• Upload image adds pictures to the gallery for this session.
• Draw opens Paint on the currently selected thumbnail.
• Add to Background slideshow sends the selected picture into the Background app queue (max 10). Set as desktop applies it immediately as a static wallpaper.
• Move to Trash sends uploads to Trash (restore or empty Trash to delete forever). Gallery cats still can’t be trashed. Regan and Gallery cat photos cannot be deleted.

Background

• Double-click Background to choose wallpaper and slideshow options.
• Tick up to 10 pictures, or use Add current from File Explorer / queue tools.
• Set Seconds between slides and Fade seconds, then Start slideshow. Stop freezes on the current slide.
• Apply static uses the photo you last clicked in the picker.

Settings

• Open Settings from the desktop or File → Settings.
• Appearance: Light or Dark theme (saved in this browser).
• Idle mascot: after ~90s idle, a cat peeks beside the taskbar; turn it off here if you prefer.
• Jump to regan.png, pick a random cat wallpaper, or set slideshow timing defaults.
• Regan Python head, Python mode (random hydra windows), and Regan talk are configured here (see Menus & native app).

Regan AI

• Regan AI (desktop or File → Regan AI…) is a small offline chat window with pattern-matched replies — not a cloud LLM. Try help, time, joke, cat fact, or roll d20.

Solitaire

• Classic Klondike: stock deals three cards per click; empty stock recycles the waste.
• Only the top waste card plays. On columns, select a legal face-up run; empty columns take a King.
• Double-click the top card of a column to auto-move to a foundation when legal.

Minesweeper

• Mini 9×9, 10 mines · Medium 16×16, 40 · Large 16×30, 100. First click is always safe.
• Regan mode: revealed cells show cat photos by number (1–8), mines, and covered tiles.
• Left-click reveal, right-click flag. Clear all safe cells to win.

Share screen

• Start capture shares a screen or window (browser permission). The video is not flipped — it matches what you shared. If the browser offers it, tab/system audio is captured too — use the Vol slider in the taskbar for playback level.
• Choose a filter (invert, sepia, blur, etc.). The live feed can include your mouse cursor when the OS includes it.
• Stop ends sharing; closing the window stops capture too.

Mirror

• Blue play area: a second pointer follows your mouse — the same pixel Windows 95 arrow as the rest of regan.exe (fun/win95-pointer.svg), drawn semi-transparent and offset.

Mouse

• The whole shell uses a chunky 1995-style pixel pointer from the fun/ folder (not the OS default arrow), except in text fields (I‑beam) and the Draw canvas (crosshair).

Browser

• Open folder (project)… loads a whole directory: Chrome uses a real folder picker (recursive); other browsers use Choose directory. The app picks index.html (or the first .html), then rewrites stylesheets (including url(…) in CSS), scripts (including ES modules / relative import), images, media, icons, and iframes/embeds to blob URLs. Open HTML file… is only for a single file. Nested HTML in <iframe src="other.html"> is not re-processed. Only open projects you trust.

Notepad

• Notepad edits plain text: New, Open… (.txt), Save as… (download). Your draft is remembered in this browser until you clear it.
• Regan mode switches a warmer theme and lets Space sometimes type regan in the pad (same odds as Settings → Regan talk), only while you’re typing in Notepad.

Taskbar

• 🐱 Regan (far left) opens the start menu: search installed apps, Open one, or Pin it to the desktop.
• Clock shows the current time. Vol adjusts volume for video / audio in regan.exe (e.g. Share screen when audio is available).

Trash & App Store

• Trash and App Store stay on the desktop (you can’t remove them). Other app icons: right‑click → Hide from desktop (keeps the app — open it from the 🐱 Regan menu or App Store) or Move to Trash…, or drag the icon onto Trash (same as Trash). Or move imported files to Trash from File Explorer.
• Open Trash to Restore or Empty Trash (permanent). Pictures are only fully deleted after you empty Trash.
• App Store reinstalls apps you removed from the desktop.
• Drag desktop icons to rearrange — positions snap to a grid (same spacing as the default layout). Drag app windows by the title bar (or by an empty strip of the window body).

Menus & native app

• File / Edit / View / Help mirror classic desktop programs.
• Native window: run python regan.py after pip install -r requirements.txt (WebView2 on Windows).
• Cursor: Terminal → Run Task… → regan.exe.
• App windows can be resized from the grip in the bottom-right corner.
• Run as administrator (Windows): sets your real desktop wallpaper to Regan and re-applies it about every 12 seconds while regan.exe is running.
• Regan Python head (hydra) in Settings: when on, each normal window close spawns two more regan.py processes. Turn it off in Settings (each copy has its own window) or end tasks from Task Manager. Killing the process from Task Manager does not spawn children.
• Python mode (native): with hydra on, each spawned copy opens at a random position on the screen (via --random-pos).
• Regan talk: Space in a text field has a 5% chance to insert regan ; elsewhere every Space shows regan in the status bar.
