With version 4.4.0, two major features were added: Local scripts and a Kiosk mode.
With the scripts, it is possible to define JavaScript, which is inserted into any websites and apps by the browser. This can be used to implement many functions, such as login via QR code and NFC as well as customizing old web applications or hiding unnecessary fields.
Kiosk mode can be used if no MDM is in use, which usually includes kiosk mode.
