Menu & Gameplay Font System

CustomWindowBrand separates font behavior into two states:

| State | Font Used |
|:–|:–|
| Outside a world | Menu font |
| Inside a world | Gameplay font |

This helps prevent oversized menu text while still allowing stylish fonts during gameplay.

Supported font modes:

Examples of Google Font names:

Roboto
Inter
Nunito
Poppins
Quicksand
JetBrains Mono
... and more!

SlowMine Integration

CustomWindowBrand includes built-in SlowMine-style arm animation controls.
You can adjust animation speed for:
Mining
Block placing
Eating and drinking
XP bottles
Ender pearls
End crystals
All arm swings at once
The slowdown is applied from the first swing frame, which helps reduce the small hand stutter found in the original SlowUT behavior.

_The mod is still under development, please contact us if you encounter any bugs or issues. Thank you._

_Regarding Google Fonts: We use a resource pack to display the fonts, so the resolution may be poor or errors may occur. We are working on improving this._

This mod actually originated from my personal desire to optimize certain interface elements and create a more cohesive game experience; it might not suit everyone's tastes, but you are welcome to request the addition of features you would like to see. Thank you for using the mod.
