Your Options Shall Be Saved (YOSBS)
by Yomna
Your Options Shall Be Saved, or YOSBS, is a Fabric utility that lets modpack creators decide which configuration files players keep when a pack updates.
What it does
A modpack author can ship default configuration files that the game creates on first launch only. After that, the mod stops touching those files, so a player's own settings survive later updates instead of being replaced by the new defaults. Files inside the config folder otherwise behave as usual.
The mod covers files such as options.txt, the settings for mods, and shader option files. Since the mod acts during pre-launch, ahead of Fabric loading the other mods, it settles how these files are treated before any other mod reads them. Authors gain full control over which configurations persist and which are reset.
Installation needs Fabric Loader 0.4.0 or newer and Fabric API, and the mod requires Java 8 or newer. Client-side only, so only the client needs it; a server can run without it. The code is open source under the GNU Lesser General Public License v3.0 only. Files are published for Fabric alone, across 47 release versions 1.14 – 26.2, with 1.0.0 for 26.2 as the latest file.
Key features
Default configs on first launch
Default configuration files are written the first time the game starts and are not applied again afterward.
Player preferences preserved
Settings a player has changed are kept when the modpack updates, instead of being overwritten by the new defaults.
Author-defined persistence
The modpack author chooses which configurations persist and which are reset, file by file.
Pre-launch processing
The mod runs before Fabric begins loading other mods, so the handling of config files is settled first.

Who it’s for: Modpack creators who need to ship default settings without erasing player choices on update, and players who want their own settings kept across pack releases.

What the author says
Your Options Shall Be Saved (YOSBS) is a lightweight utility mod that lets modpack creators define default configuration files without overwriting player preferences YOSBS solves this by copying any file placed in config/yosbs/ to its proper location only once on first launch — and never again
