Today, we released a new Flow feature -- a side rail, which holds the content that was previously in the header, at the top of the page. You can choose to close the side rail on a board, which gives you an almost-full-screen width for the board.
There are two problems that the side rail is intended to address.
First, we know that it's important to have announcements, warnings and metadata easily available at the top of the page. At the same time, the header boxes can get very long on an article talk page, pushing the conversations well below the edge of the screen. This is baffling for new users, and it can be a hassle for experienced people, too. Putting those templates and instructions in the side rail keeps them visible, without getting in the way of the discussions on the page.
Second, we've had lots of feedback about the fixed width on Flow. Some people like the fixed width and some don't, and we wanted to give people more choice. The side rail gives us an opportunity to add a toggle that changes the display width.
There's one piece that's coming soon -- the toggle should remember the last state that you've chosen, across all the Flow pages that you visit. Right now, it gives you the default on every page, with the side rail open. We're going to add that preference in a few weeks.
So what do you think -- helpful or not?
