Editor Fullscreen lets you instantly switch your Game View into a true borderless fullscreen window — not just Unity's built-in "Maximize on Play" which only expands within the Editor frame.
Perfect for:
• Testing UI/UX at real screen resolution without building
• Presenting gameplay, cutscenes, or VFX to stakeholders
• Streaming or recording editor gameplay at native resolution
• Quick playtesting with an immersive full-screen experience
How it works:
Press F11 (or click the toolbar button) and your Game View pops out into a dedicated borderless window that covers the entire monitor — title bar, taskbar, and all editor chrome disappear. Press F11 again (or Escape) to return to the normal editor layout instantly.
Everything lives inside the Editor/ folder so absolutely nothing is included in your final build. Your game's size and performance are completely unaffected.
