SAFE Beaker Browser Updates (0.4.0)

Hi I was looking at these SAFE Browser / safe-js examples and have some been removed?

I remember there being more.

Specifically, I was looking for the safe-js commands that dealt with StructuredData and AppendableData (which are kinda mentioned half way down on here).

I thought I remembered seeing them in the examples.

Are there any examples for them that I can see and learn from? Examples of things like window.safeStructuredData that would show what kind of inputs they need and context / use cases. Thx!
