In case you missed it, Umbraco 8 dropped almost by surprise in the last week of February.
Along with a massive refactoring of lots of code of which I have absolutely no understanding, v8 introduces something I do understand - Content Apps.
Since you're reading Skrift, I'm hoping you're up to speed with the latest and greatest from Umbraco HQ, and content apps (or the term, at least), aren't an entirely new concept. If you're reading this and thinking 'Content Whats?', duck over to the Umbraco documentation and read up on the shiny new feature.
Content apps are beautifully described in that documentation as 'companion read-only information relating to the current content item in the Umbraco backoffice'.
Note the emphasis on companion and read-only. Content apps are not an interface for updating a node, but for supplying additional information for making our editors' jobs more pleasant.
