Everybody use mobile phones more and more.
Often the function of the Dashboard is to give fast overview about something. We see in our everyday workflow more and more, that people would like to get the first information/ overview from Mobile (not only from Desktop anymore).
Please consider the opportunity to add for Dashboard a functionality to set up a mobile view (like Experience Builder already have).
At the moment the only way to make the Dashboard usable from desktop and for mobile phone is to set up two different dashboards.
