I understand that auto pop-up of interface on incoming call is not possible, apparently it was designed to be kept open on a second screen. But what if you are already working on both screens and keep covering the phone up? it takes time to navigate to flashing icon and than to answer button, min 2 rings. I believe that auto pop-up on incoming call and or feature allowing you to lock the interface over all open windows regardless of activity are basic, very useful and not difficult to program. I wish I could see them in the next update
