Some examples relate to facilitating multi-tasking in a computing environment. A focus area component defines a focus area within a display space—the focus area occupying a subset area of the display space area. A scaling component scales display objects as a function of proximity to the focus area, and a behavior modification component modifies respective behavior of the display objects as a function their location of the display space. Some implementations provide for interaction technique(s) and user interface(s) in connection with managing display objects on a display surface. Further, some examples define a central focus area, such that the display objects are displayed and behave as usual. Also included is a periphery outside the focus area where the display objects are reduced in size based on their location, getting smaller as the display objects near an edge of the display surface with many more objects visible.
