Observable’s notebook layout lends itself really well to prose and full-width visuals.
My data is less interesting, a lot of repetitive graphs with low visual fidelity. I also have a desire to fit it all on one screen for use on monitors hanging in the office.
One way to make the presentation flow better for my use case is a 2-column layout. Although something more generalized like a gridstack or spreadsheet layout would also capture it.
The other thing that would be nice in these multi-column situations is to make the layout responsive to the browser itself going fullscreen, which is a different behavior than the built-in fullscreen option.
