Kiosk mode can be enabled by setting `kiosk: true`, `autoHideMenuBar: false` and `fullscreen: false`. More options can be found [here](https://github.com/electron/electron/blob/master/docs/api/browser-window.md). This will most likely be used in advanced installations, below.                                                                | []                                         |
