Feature request - Snippets

We are currently populating internal documentation for our business, and one challenge we are facing is reducing duplication of content across mostly similar documents.

For example, we have a comprehensive collection of job specifications for every role in our business. While each one is different overall many share common content (eg: senior responsibilities are the same for all senior roles) which we are currently copy+pasting.

Obviously, this gets hard to maintain, really quickly.

So, I'd like to suggest a new 'snippets' feature. The idea being that you create and manage snippets of content (with all the usual formatting options) within a snippets area. These can then be included in another document using the usual UI. When viewing a document, you'd never know it was a snippet, but while editing, it could be faded and show a message stating 'Edit this snippet'.

Thoughts?
