My only real problem is there's no debug tab for errors from the console. Without those errors, I have literally no idea why projects won't run. I would probably place a debug tab as a switchable tab with the sprite "folder" selection menu.

I think this is a great idea and will probably implement it exactly as described.

It seems like console-feed is the best package for embedding a Chromium-style console into the page: https://www.npmjs.com/package/console-feed
