there's nothing better than this!
but there's still something lacking.
first,if i choose one contact and i found that it's not the right one i want,i need to use my thumb to click the left soft key(hard or soft).it made me feel uncomfortable.for this, i recommend to add one feature that i can use my thumb to drag on the left side to back to the main screen.
second, in the main screen,on the right side,there's a quite big space.you can add something like groups or others.
third, in the contact chosen screen, there will be buttons with phone numbers on them.but it's not friendly, i think you can add some icons on them,that makes it directer.
last, please make a cab that i can use it earlier.
thanks a lot.
regards.
