Example of simple Scriptable Widget per topic

Since 2 weeks I have discovered the Scriptable Widget.
I like the Example Widgets already posted, still I mis the Example per Topic in the Document Help.
Let’s say: Create a Simple widget with:

  • just the time in a specific format,
  • or get an Image from the Local Documents.
  • or … whatever the users wants to see appear in the widget, but only that topic.
    For experience developers, probably a piece of cake, for us beginners, a super library that explains the “Document Help” of the Scriptable App.
