The "debug console" element is confusing

[T3sT3ro]

This element that is supposed to look like dev-tools in the result window is confusing. It doesn't provide any useful info, it has some layout problems, it makes the UI more clunky and it doesn't work on mobile. It also sometimes shows "Script error at 0:0". I didn't find any good usage example for it yet. I think it would be beneficial to just remove it.

Maybe use a specialized embedded frame for managing those input/result boxes with jsfiddle/codepen/codeSandbox/Glitch if it's possible?

The input window would also benefit from some more styling. It awkwardly blends right into background on dark theme:

Even a simple rounded border with shadow would work imo:
