Fullscreen Windowed (Borderless) for Minecraft 
This mod is a very simple addition to the game that will allow you to make your game run in borderless windowed instead of the default fullscreen available in Minecraft.
Advantages of borderless windowed versus default fullscreen
- You can just hit Escape and use your other monitors without minimizing the game
- You can alt+tab out of the game more smoothly
- You can have other windows on top of the Minecraft client when it's not active
