Hi tushma,
the "create application shortcut" feature has been replaced with "add to taskbar" which will add app shortcuts to the Google Apps Launcher or into the Chrome taskbar (ChromeOS) or Windows taskbar (Windows).
To create an Application Shortcut yourself, you can use the following procedure:
- * Copy the Chrome Icon shortcut to the computer desktop
* Right-click the copied icon and select "Properties"
* In the Target box, at the very end put a space and then --app=http://runeaudio
http://runeaudio can be replaced with your PIs ip address.
If you like you can replace the icon with something like this:
