I definitely missed this feature, you have my thanks!
It’s not ideal in that it displays the entire value of the content instead of a diff, making it hard to use if a single Text column holds the contents for a page.
But, it definitely solves part of my issue!
I’m curious which specific features from your original post are most important for your wiki scenario?
My primary issue at the moment is that if I use a row per page, and a single Text column to hold the “primary” content of the page, it’s very hard for users to style the page as they want.
E.g.: Most users come from other wiki setups or even Google Docs, and in my usecase I want to enforce certain (data) structure on the users, but allow the page styling / content up to them. (Positioning images, etc).
