I shutdown app and then started it again. Double tap now works in widget - which is all I plan to use. What I see as major problem is lack of possibility to specify which number exactly will be dialed when double tapping on contact. Also application is not recognizing correctly which number is cell and which fixed, although these are correctly labeled in built in app(and thus in corresponding DB I suppose). I think you have mentioned that it is problem with mobilityQT?
Another small notice - when I am scrolling through desktops I occasionally tap on group icons on the left side of the widget and thus switching it to this group tab view. So when I return to wodget desktop I have to tap on the most frequently used group. All other objects on desktops don't have that behavior.

PS. I really appreciate your work and the way you are communicating with testers and discuss and implement is exemplary!
