ServerPackOverlay

Pack Priority Override is a Fabric client-side mod for Minecraft 1.21.11 that lets specially-marked resource packs be positioned above the pinned server resource pack — something vanilla normally prevents.

By default, pinned resource packs (such as a server-provided pack) are locked in place: you can’t drag any other pack past them in the resource pack selection screen. This mod adds an opt-in way around that restriction for packs you explicitly mark.

Features:

• Client-side only — no server installation required, safe to use on any server.
• Opt-in via a hidden description marker (§kSPO), so it never affects normal resource packs.
• Marked packs are automatically promoted above pinned packs whenever the pack list changes — including when a server sends its resource pack after you connect.
• Resources are automatically reloaded whenever the pack order actually changes, so promoted packs take effect immediately without a manual reload.
• The pinned pack itself is never moved or disabled; only the marked pack’s position relative to it changes.

How to mark a pack:
Add the marker to the start of your pack’s description field in pack.mcmeta:

{
“pack”: {
“pack_format”: 71,
“description”: “§kSPO§rYour Pack Name”
}
}

The §r right after the marker resets formatting so the visible pack name displays normally — only the hidden SPO marker itself appears obfuscated in the pack list.

Compatibility:

• Minecraft: 1.21.11
• Loader: Fabric
• Side: Client only
