Is creating new properties and adding tags to multi_select supported?

[benthecoder]

Hi there, thank you for making this library it's really useful.

I have three main questions.

1. Is creating a new property supported with this sdk?
2. Is adding new tags to a multi_select property supported?
3. also any idea how to get the contents of the pages itself? I only see the title and properties for some reason.

Apologize in advance if some of these questions are stupid

Thank you.
