The video was really good, and the UI looks fun too.
If I understand correctly, is this not as useful for frameworkless html/css/js development? Since when you make edits using browser-built-in-devtools it can and does modify the actual css files (in-memory, of course) which you can use to copy-replace with entirely (assuming no build/bundling step aswell).
If so and this allows you to use any framework and still have that kind of workflow, that's fantastic. Half the reason I don't like using frameworks is because I lose the built-in WYSIWYG editor functionality. Guess I'd still lose the usefulness of the built-in js debugger, tho :(
Yeah I mean you can basically achieve this set up even with frameworks, if you're using stylesheets, but it's the copy/pasting and finding source code that is usually the pain. With this you just press apply (or enable auto-apply) and your agent gets to work. You can also edit the content, add/remove/reorder elements etc, I don't know how good the browser dev tools are at writing all that back though.
