# Built-in features LINE MINI App comes with the following built-in features: ## Action button By default, an action button is displayed on the common [header](https://developers.line.biz/en/docs/line-mini-app/discover/ui-components/#header) provided on every page of your LINE MINI App.  When the user taps the action button, either the [multi-tab view](https://developers.line.biz/en/docs/line-mini-app/discover/builtin-features/#multi-tab-view) or the [options](https://developers.line.biz/en/docs/line-mini-app/discover/builtin-features/#multi-tab-view-option) will be displayed depending on the LINE app version. In LINE version 15.12.0 or later, the multi-tab will be displayed, and in LINE version earlier than 15.12.0, the options will be displayed. **Tip** - You can implement a [custom action button](https://developers.line.biz/en/docs/line-mini-app/discover/custom-features/#custom-action-button) and place it anywhere you want in the format of your choice. - New features, such as the ability to move back and forth between multiple chat rooms without closing the LINE MINI App, are underway. - You can't hide the action button on the LINE MINI App. Also, **Module mode** can't be set for LIFF apps added to a LINE MINI App channel. ## Multi-tab view The multi-tab view displays options for the LINE MINI App currently in use and recently used services. 1.
