### What should this feature add?

It would be nice to have the interface be able to scale across widescreen displays a bit better. The existing side panel is stacked vertically and set to fit 100% across whatever it's width is. But it would be helpful if, past a certain view breakpoint, there was a max-width for each section, and it could stack a grid horizontally (maybe two columns).

I have a personal custom CSS rule to _kinda-sorta_ hack this in right now, but it's far from elegant at the moment. (Each grid cell is as tall as the tallest one in the row; I didn't futz around much further than this.)

Here's what _that_ monstrosity currently looks like:


Food for thought. Hardly a pressing concern. Just a 'nice to have', if someone's bored. :sunglasses:
