Good job on the website, it sells the app well. The app itself is quite cool too.
Feedback: When you press "backspace" to delete smthg on the canvas, it loads the previous visited page (browser default behaviour). On Firefox, mac OS.
Valentin, thanks a lot for taking the time and let is know this, we did a lot of work improving the shortcuts, but due to the huge range of options, still some bugs. Thanks, it will be fixed soon :)
