It would be very useful to have an option to add screen padding.
Case: I have a screen with multiple controls in it. If my app width will be bigger than 1366px I want controls to be aligned to center of a screen (instead of aligned to left). Currently to achieve that I need to X and Y of every control on every screen on every app of mine...which obviously is very inefficient and time consuming in futher development.
I tried to use groups but groups does not have padding option + it propagates its config to all controls (when I set X property in a group control each control in the group has also set X property)
