When I took a look quickly, it also shows the "Spotted a bug? Drag me there!" every time the page loads - which could quickly get overwhelming, and make the user wonder why the developer is so certain that they will run into a bug. (Why do developers not make "report a bug" obvious? Because just seeing it implies there are enough bugs that a link is necessary.)

I also have no idea how well this works on mobile - and seeing that the Pro plan doesn't remove attribution seems like a mistake.
