 This guide documents frontend configuration options that control various UI behaviors and features in SciCat. These settings are defined in the configuration file specified by the `FRONTEND_CONFIG_FILE` environment variable (default `src/config/frontend.config.json`).
 
-**TODO:** Many of these configuration options were added a long time ago and may no longer be in use. This documentation should be reviewed and updated to reflect the current state of the application and remove obsolete configuration flags.
