Settings

Click the Settings entry at the bottom of the sidebar (or click the version number at the lower left) to open the settings page. It's made up of four cards, with an additional theme-switcher shortcut at the bottom of the sidebar.

Interface Language

Switch among Chinese / English / Japanese; the change takes effect after you restart the app. The language chosen in the first-run wizard is recorded here as well.

Game Path

• Browse to select the game's directory; the app validates that the directory is usable;
• Supports one-click open of the game directory;
• After a path change, both local mod scanning and "Launch Game" automatically use the new path.

Check for Updates

The app has a complete built-in auto-update system:

• The "Check update" button has three states: checking (spinner) / downloading (turns into "Cancel download") / idle;
• When a new version is found, it shows vcurrent → vlatest and offers three download channels:

Channel	Description
Default source	The app's built-in source, downloaded as a background task
GitHub source	Auto-resolves the Releases direct link and verifies the version matches
Open Quark Drive	Opens the share link in your browser to download it yourself

• Downloads run as background tasks with a progress bar, downloaded / total size and live speed, and can be cancelled at any time;
• Once downloaded, choose "Restart & Update" now or "Later" — the update applies automatically at next launch, with no manual reinstall needed;
• Stale installers are cleaned up automatically and failures back off, so the whole upgrade experience is worry-free.

By default, the app also silently checks for new versions on every launch and downloads them in the background over multiple threads; once a new version is ready, a red NEW badge appears next to the version number at the bottom of the sidebar.

About

• Opens the GitHub repository (b9348/sfmmm);
• Issues and suggestions are welcome as feedback;
• An acknowledgements card sits at the bottom.

Theme Switcher

At the bottom of the sidebar (above the Launch Game button) you can switch the interface theme quickly:

• ☀️ Light
• 🌙 Dark
• 💻 Follow system

The theme choice is persisted in the local database; the app follows the Fluent Design style, with both light and dark themes fully adapted visually.
