WindowX
by XuTrain
WindowX lets commands control the Minecraft client window itself, moving, resizing, shaking and animating it through a set of functions.
What it does
Commands move, resize, zoom, maximize, minimize and switch the game window to fullscreen or borderless. Position changes can be animated with more than thirty easing functions, and window effects such as shake, encircle, breathe and wobble run on top of them. Physics settings for gravity, friction and bounce are also available for the window.
Some features reach outside the game. The full version can send system notifications through native Windows, macOS and Linux channels, while the basic version shows only in-game toasts. A separate toggle hides the HUD, and mouse position can be moved and animated through commands. Scoreboard integration exposes window and mouse properties.
WindowX is a NeoForge library for 1.21.1 and needs MCEF (Minecraft Chromium Embedded Framework) when that optional dependency is used. It runs on client and server, so both need the mod. The code is released under the Apache License 2.0, but the project is not open source.
Key features
Command window control
Commands change the game window's position, size and display mode, so scripts and command blocks can drive it.
Easing animations
Window movement can follow one of more than thirty easing curves, with shake, encircle, breathe and wobble effects.
Physics simulation
Gravity, friction and bounce can be applied to the window so it reacts over time instead of snapping into place.
Notifications and HUD toggle
The full version sends native system notifications, and the F1 key hides the HUD while a scene is shown.

Use cases
Who it’s for: Map makers, adventure creators and server owners who want the client window to respond to commands or scripts. Players who only want a standard window setup do not need it.
