With this new update, you will be able to keep the whiteboard at full screen - even with refreshing the page! 

To access this from a Windows computer, press full screen on the Smart Flow Whiteboard, then press 'F11' on your keyboard to toggle between persistent full-screen mode and regular whiteboard screen. 

For a Mac user, you can press 'Command'+'Control'+'F'. Please note that Microsoft Edge does not support this feature. 

Chromecast users select the cast tab and then press the Smart Flow full-screen icon (not the browser full-screen option). There is no need to press the additional buttons required for non-chromecast users.
