BentoScreen

Menu-bar app for macOS: one hotkey puts every app of a layout in its slot.

• ctrl+opt+1 Agent: browser top-left (2/3), chat bottom-left (1/3), Claude / Zed / iTerm2 right half
• ctrl+opt+2 Half / Half: browser left, the rest right

Snap the focused window, ShiftIt-style — press the same key again to cycle ½ → ⅔ → ⅓:

• ctrl+opt+cmd ←/→ left / right part, full height
• ctrl+opt+cmd ↑/↓ top / bottom part, same column
• ctrl+opt+cmd 1/2/3/4 top-left / top-right / bottom-left / bottom-right corner
• ctrl+opt+cmd M fill the screen
• ctrl+opt+cmd C center, same size
• ctrl+opt+cmd N move to the next display

Edit ~/.config/bentoscreen/layouts.json, then menu bar icon → Reload Layouts. Each slot is a list of apps (name or bundle id) and a rect as fractions of the screen, x,y from the top-left:

{ "apps": ["LINE", "Discord"], "x": 0, "y": 0.6667, "w": 0.5, "h": 0.3333 }

Layouts apply to the screen under the mouse. Apps that aren't running are skipped.

Install

Unzip, move BentoScreen.app to /Applications, open it, and allow it under System Settings → Privacy & Security → Accessibility. Release builds are self-signed, so the first open needs Privacy & Security → Open Anyway; the Accessibility grant survives updates. To start it at login: menu bar icon → Open at Login.

Build

./build.sh → build/BentoScreen.app + .zip (universal). It signs with the BentoScreen Dev code-signing certificate from your keychain (create a self-signed one in Keychain Access), or falls back to ad-hoc, which loses the Accessibility grant on every rebuild. SIGN_ID="Developer ID Application: …" ./build.sh signs with another identity; SIGN_ID=- forces ad-hoc.
