Really loving the tool so far Cedric!
Just wanted to chime and say one way I think it could be even better for fast prototyping would be to have TypeScript definitions available, and maybe an option to set TS as the scripting language in Editor in Project Settings.
I'd be happy to help with these features if you're looking for contributors (good way to get familiar with the API, and I'd really like to get a peek at that Editor code XD).
