Custom shortcuts support

Is your feature request related to a problem? Please describe.
You can make a shortcut in some apps to specific items, and it creates an icon on your home screen. Baldphone doesn't support this.

Describe the solution you'd like
Enable on the right screen (where favourites are) for the shortcut icons to be added. An example would be in one video surveillance app i can create a shortcut icon to a specific camera on a home screen in a stock launcher. So if i added such an icon to the home sccreen from the app, it could put the shortcut automatically into the "favourites" screen where contacts and apps can be favourited.
