Code before:
    let config_path = options.config_file.clone().or_else(installed_config);

    // Load the config using the following fallback behavior:
    //  - Config path + CLI overrides
    //  - CLI overrides
    //  - Default
    let mut config = config_path
        .as_ref()
        .and_then(|config_path| load_from(config_path, config_options.clone()).ok())
        .unwrap_or_else(|| {
            let mut config = UiConfig::deserialize(config_options).unwrap_or_default();
            match config_path {
                Some(config_path) => config.config_paths.push(config_path),
                None => info!(target: LOG_TARGET_CONFIG, "No config file found; using default"),
            }
            config
        });

    after_loading(&mut config, options);

    config
}

/// Attempt to reload the configuration file.

    let mut config = load_from(config_path, config_options)?;

    after_loading(&mut config, options);

    Ok(config)
}

/// Modifications after the `UiConfig` object is created.

Review comment (bug):
```suggestion
    debug!("Reloading configuration file from: {:?}", config_path);
    
```

I'd add a newline, just to create some separation.

Code after:
    let config_path = options.config_file.clone().or_else(installed_config);

    // Load the config using the following fallback behavior:
    //  - Config path + CLI overrides
    //  - CLI overrides
    //  - Default
    let mut config = config_path
        .as_ref()
        .and_then(|config_path| load_from(config_path, config_options.clone()).ok())
        .unwrap_or_else(|| {
            let mut config = UiConfig::deserialize(config_options).unwrap_or_default();
            match config_path {
                Some(config_path) => config.config_paths.push(config_path),
                None => info!(target: LOG_TARGET_CONFIG, "No config file found; using default"),
            }
            config
        });

    after_loading(&mut config, options);

    config
}

/// Attempt to reload the configuration file.
pub fn reload(config_path: &Path, options: &Options) -> Result<UiConfig> {
    debug!("Reloading configuration file: {:?}", config_path);

    // Load config, propagating errors.
    let config_options = options.config_options.clone();
    let mut config = load_from(config_path, config_options)?;

    after_loading(&mut config, options);

    Ok(config)
}

    config.generate_hint_bindings();
}
