Rent Server with this Mod

About this Mod

This mod replaces the default Minecraft fullscreen with a borderless window. This is great for multi-monitor setups because it stops the game from minimizing when you click on something else.

Installation
Just drop the JAR file into your "mods" folder like any other Forge mod.

How to use
When you press F11 or turn on fullscreen in the settings, the mod will automatically handle making it borderless windowed for you instead of the default version.

ty to those who use my mod :)

Any issues please let me know i will get it fixed ASAP.
