Key advantages for modded Minecraft

• **One-Click Mod Loaders:** Switch between Fabric, NeoForge, Forge, and Quilt inside any instance's Version tab.
• **Built-in Mod & Modpack Browser:** Search and update Modrinth and CurseForge modpacks, shaders, and resource packs directly inside the app.
• **Automatic Java Management:** Pair Java 21, Java 17, and Java 8 per instance so modern 1.21 packs and classic 1.12.2 packs both launch cleanly.
