Not sure how much I'm into this. Might be helpful to speak for it more than just the screenshots? 😂

From what I can tell in the source, you've switched to a two column layout, with data input on the left 40%, and display on the right 60%. Then for the JSON displays, you've put the download buttons inline by creating two subcolumns, 80% for the preview and 20% for the download button.

Since you've only edited the Jinja template, that'd mean there's no opt-out here.

I get the desire for this, it feels like the horizontal real-estate is going to waste with one column. However,

1. It looks a bit busy for my taste.
2. The horizontal real-estate for the figures is reduced.
3. It seems likely that folks might create lots of UDFs. Judging from the screenshots, you'd quickly scroll past the convenient input-output side-by-side, and then be back to effectively a single-column layout, where the figures are smaller and off-centre.

I think this could be nice, but I'd want to toggle it, and I think we need to give some thought to scaling with content (and perhaps screen-size?)
