A small addon for Blue Skies by Modding Legacy. It adds two config options, both off by default. With no config changes, this mod does nothing and Blue Skies behaves exactly as it ships — this mod is not a replacement or a fork, just an optional switch layer.

Config options (config/moe_discsvillagers-common.toml):

disableTradeSwap — Blue Skies re-rolls villager trade offers inside Everbright/Everdawn to its own dimension-themed items. Turning this on skips that step, so trade offers set by other mods (e.g. Custom Villager Trades) aren't silently overwritten. Villagers keep their Blue Skies look either way.
fixDiscTooltip — Blue Skies' three music discs (Blinding Rage, Defying Starlight, Venomous Encounter) hardcode their tooltip subtitle in Java, so no lang file or resource pack can ever change it. Turning this on makes the subtitle read from a normal per-item lang key instead (item.blue_skies.<id>.desc) — the same convention vanilla's own music discs already use. With the option on and no override present, the tooltip text is unchanged; this only makes it overridable like every other item in the game.

How it works: both options are implemented as a Forge coremod that patches Blue Skies' own class files in memory at launch. With an option off, the patched method immediately falls through to Blue Skies' completely unmodified bytecode — there is no behavioral difference from stock Blue Skies unless you explicitly flip a switch in the config file. This mod does not bundle, redistribute, or fork any Blue Skies code.

Licensing: Blue Skies is licensed under Modding Legacy's General Terms (all rights reserved, addons permitted). This mod is an addon in that sense — it never redistributes Blue Skies source or assets, only modifies the user's own separately-installed copy at runtime, and every behavior change is opt-in. See NOTICE.txt in the jar for the full explanation.
