Windowed Fullscreen Mod (26.2, 1.21.1) – Borderless Windowed Mode

Windowed Fullscreen Mod enables a borderless windowed mode for the game. This mode allows Minecraft to run in a window without borders, giving the appearance of fullscreen while still allowing you to easily switch between applications or use multiple monitors. It’s particularly useful for multitasking or keeping other windows visible while playing.
