Feature request: Dark mode

A dark mode option would be appreciated.

When I am using the plugin, I usually open it on a separate tab on my second monitor and keep it open while I work. The white background covering all of the screen makes it very bright.

What I do currently is I switch to an empty browser tab in the downtime when I am not using the console.

If I may sneak in a second suggestion here: word wrap, applicable for both the Input and Output panels, would be useful.
