Pull request changelog

App

Added

• Added options.txt syncing and editing in the Modrinth App, keeping game settings consistent across Minecraft versions.
• Added optional resource pack syncing, disabled by default, which shares packs, enabled states, and load order across participating instances.
• Added Sync and Desync actions, status indicators, and cross-instance change warnings for resource packs in the Content tab.
• Added per-instance sync overrides for game settings and resource packs.
• Added an update notice explaining the expanded syncing features and letting existing users choose whether to start syncing and select a source instance.
• Added a Features settings tab for controlling optional parts of the Modrinth App interface.
• Added Features controls for showing the Skin selector in the sidebar, limiting Quick instances, and syncing feature settings across devices.

Changed

• Moved the Files, Worlds, and Screenshots tab controls from individual instance settings to Features settings, where they apply to every instance.
• Moved "Show all screenshots in sidebar" and "Show Jump in section" from Behavior settings to Features settings.
• Improved modpack installs and updates to preserve unsynced options.txt values while reapplying synced game settings.
• Improved resource pack syncing to skip incompatible instances and show packs whose changes are waiting to be applied.
