Legacy Borderless
by Teknicallity
Legacy Borderless swaps Minecraft 1.6.4's exclusive fullscreen for a borderless windowed mode on Forge.
What it does
Legacy Borderless replaces the exclusive fullscreen of 1.6.4 with a borderless window that covers the monitor exactly and has no title bar. Exclusive fullscreen can black out the screen when a player alt-tabs, while this window keeps other windows visible behind it and avoids that blackout. A key bound to F11 by default toggles the mode, the key can be rebound, and the game remembers whether borderless was on when it was last closed. The mod runs on Windows only and is released under the MIT License as open source.

Rebindable toggle
A key, F11 by default, switches the mode on and off, and the choice is kept between sessions.

Alt-tabbing never blacks out or minimises the game, other windows can sit on top, and there's no title bar to burn in on OLED. Toggle it with…
