We're releasing a new Flow feature today on mediawiki -- a Table of Contents, which is designed to help people browse and navigate around a Flow board.
As you scroll down on a Flow board, you'll see a persistent header that gives you access to the Table of Contents, wherever you are on the page. You can scroll around using the Table of Contents, and hop quickly from one topic to another.
The current feature is version 1 -- there are a few more tweaks that we want to make, so there will be a v2 coming. This is also a milestone on the road to Search -- we're going to build the feature to search on a Flow board on top of the ToC feature.
It's going live here a little later today. I'm looking forward to hearing what you all think of it!
