Advancement Plaques is a mod for Minecraft that replaces the standard advancement popups with a fancier, more prominent glowing plaque. The goal was to make advancements feel more important, and I always liked how achievements look in games like Diablo 3 and World of Warcraft.
There are many configuration options available, including visual and functionality options, and the mod is compatible with all modded advancements. The look of the plaques is also completely customizable with resource packs.
Download the mod on CurseForge or check out the source code on GitHub.
