Exemplary methods, apparatuses, and systems receive user input to move, resize, or add a first user interface object to a first location in a user interface window. The user interface window includes a second user interface object in a second location. In response to the user input, constraints are generated based upon the first location and the second location. The constraints define a size or a position of the first user interface object relative to the second user interface object. The first user interface object is displayed within the user interface according to the determined constraints.
