User reviews
Okay tool I would say, but it would have been nice if the GUI was reworked a bit, and if it actually supported the `window.addEventListener(func)`. For me this never triggers, and I have to sometimes run the code at a point that it only affects part of the page because other elements have not fully charged yet.

It works, but after page reloaded you need to paste code and save again.
