Allow user-entered margins and padding around text boxes and graphic/shape bounding boxes
There should be an option in the panel to increase the size of the bounding box and the way it snaps to the grid and content around it. The side panel (where user enters text size) should have a way to pad and add margins on all sides of a box or only certain few. This would translate better in the design specs as well as it would get designers in the mindset of a developer more explicitly.

Along with other components, having text containers or title containers etc with margins/padding.
When updated in component it auto retracts or pushes the elements around it reducing the need to go in and edit all the margins/padding by hand on every document.
