 **`externalStyleSheet`** | `string`  or `string[]` | _Optional_ | Either a URL to an external stylesheet or an array or URLs, which can be applied as themes within the UI
 **`customCss`** | `string` | _Optional_ | Raw CSS that will be applied to the page. This can also be set from the UI. Please minify it first.
 **`hideComponents`** | `object` | _Optional_ | A list of key page components (header, footer, search, settings, etc) that are present by default, but can be removed using this option. See [`appConfig.hideComponents`](#appconfighideComponents-optional)
+**`enableMultiTasking`** | `boolean` | _Optional_ | If set to true, will keep apps open in the background when in the workspace view. Useful for quickly switching between multiple sites, and preserving their state, but comes at the cost of performance.
 **`allowConfigEdit`** | `boolean` | _Optional_ | Should prevent / allow the user to write configuration changes to the conf.yml from the UI. When set to `false`, the user can only apply changes locally using the config editor within the app, whereas if set to `true` then changes can be written to disk directly through the UI. Defaults to `true`. Note that if authentication is enabled, the user must be of type `admin` in order to apply changes globally.
 **`enableErrorReporting`** | `boolean` | _Optional_ | Enable reporting of unexpected errors and crashes. This is off by default, and **no data will ever be captured unless you explicitly enable it**. Turning on error reporting helps previously unknown bugs get discovered and fixed. Dashy uses [Sentry](https://github.com/getsentry/sentry) for error reporting. Defaults to `false`.
 **`sentryDsn`** | `boolean` | _Optional_ | If you need to monitor errors in your instance, then you can use Sentry to collect and process bug reports. Sentry can be self-hosted, or used as SaaS, once your instance is setup, then all you need to do is pass in the DSN here, and enable error reporting. You can learn more on the [Sentry DSN Docs](https://docs.sentry.io/product/sentry-basics/dsn-explainer/). Note that this will only ever be used if `enableErrorReporting` is explicitly enabled.
