GlideUI

GlideUI is a client-side Fabric mod that adds smooth open/close animations to inventory-style GUIs (player inventory, chests, furnaces, anvils, and other container screens). Because it hooks the shared AbstractContainerScreen base class, it works automatically with modded GUIs and screens added by other mods, inspired by flow mod!

Features
Ease In / Ease Out animations when opening and closing GUIs, each with:
An easing type (Linear, Sine, Quad, Cubic, Quart, Quint, Expo, Circ, Back, Elastic, Bounce — In/Out/InOut variants).
An animation type (Expand Middle / Middle Left / Middle Right / Top / Bottom, Slide Left / Right / Up / Down).
A configurable duration in milliseconds.
Background tint — configurable color that fades in with the animation.
Background blur — configurable intensity (0–100%) that ramps in with the animation.
Compatibility controls — master toggle, toggle for modded GUIs, creative inventory, and a per-screen class blacklist (editable in the config file).
Configuration
The config is stored at config/glideui.json and can be edited in-game via modmenu mod.

The in-game screen has two tabs:

Transitions — background tint/blur and the Ease In / Ease Out settings.
Compatibility — master enable toggle and mod-compatibility options.
