Hi @Stefan_Huber!
We’re working towards sub-doc sharing and know this is a top request. Many requests to share pages are for pages with data on them, where it’s important that users see only the data shown in views on that page.
We’re focused on those use cases first, and one of the key goals in our work to separate data from docs is to make it possible to share parts of a table without sharing the full doc or table.
We’ll enable ways to share views of data directly first, then over time add the ability to share pages of text content or mixed text and data as well.
