Very interesting I'm going to try it out. What's the app written in? It has a VSCode feel to it (which is great!)... Any chance it's built in typescript like VSCode too? I'd love to write a JavaScript extension or two to customise it in the future if that's the case. Can you share what it's built with and what the future extensions will need to be built with? Thanks!
