We like the simplicity and it is very promising. However, in its current form, the backend is laggy and - more seriously - buggy. Settings are not stored and that is just simply annoying and unnecessary.

Another downside form what we did expect: On HTML you can implement this as a button somewhere. If you want a sticky widget, however, like at the right screen border you will need to put in some own dev work which we simply did not want to invest. We are very used to this just happening out of the box. Are we expecting too much?
