Fixed experience level not getting modified with the hotbar group.
1.21.1 backport
Minimized mixin usage for compatibility with Noxesium v3 which was recently released.
Major improvements.
Should be compatible with any mods now, no matter how they change the vanilla HUD layout.
Fixed Items and Debug Pie being brighter than other HUD elements when opacity is set at a low value.
Fixed Debug Pie not being repositioned with the other parts of Debug Screen.
Fixed Buttons not showing tooltips after they are clicked.
Backported all the enhancements to v1 and v2 (if possible).
You may need to manually reapply the config, like for v3.
Also fixed v1 not being able to run on 1.21.3 NeoForge.
May be the last releaase of MC 1.21 lifecycle, if there's no major issue arisen.
Config Screen Enhancements:
There is now a "Back" button which discards your value changes.
Buttons now show Yes/No instead of ON/OFF.
Improved HUD elements repositioning. This should fix some rare visual flaws.
Fixed tooltip not correctly positioned if a widget is selected using keyboard.
Christmas Release
