I wish that it were possible to select multiple views and change Text Styles and Button Properties as it is possible to change Height/Width of multiple selected views. Please tell me if that feature already exist.
to start with -> you can do this with only exactly the same type of controls if you wish. If I want to change the rounded corners of all buttons on a screen, currently I need to iterate over all buttons. Selecting all buttons, and doing it once would be much nicer.
