In previous threads its been asked about options for changing whether code appears before or after the cell content:
I understand this has been discussed greatly by design team about how a user preference could create conflict with the design intention of the notebook authors. However, could it perhaps be a control for notebook authors themselves when they pin a cell open that they can pin it open either below (default) or above (a new option)? This would mean that each author could decide how to show it, and a user can always manually “un-pin” as they wish or “pin-reverse” any cell in any notebook.
You could even experiment with different pin options, like pin-left or pin-right of the cell for a side-by-side view of content. Maybe even something like “pin-float” that makes the cell code editor live “above” the notebook content and be draggable in the nearby html… but maybe some of that is getting a bit extreme
But basically, I think “pin direction” or “pin style” could be a further cell option explored in the future and it looks like an easy enough itch to scratch for people.
