I tried that out. For some reason the notification doesn't pop up after I run the program, is that intended?
Currently that is obscure the same way the current dash launcher is. We would need at least to pop up that notification right after logging in, and then hide the notification if users clicks on it (outside the Install button). Ideally it should be clear that the button is still available to the user even if I dismiss the notification (I'm not sure how to do that).
Another question is what happens if user doesn't dismiss it, what about other notifications, do they just queue and don't show up?
