The Quickedit overly icons give access to the most important functions with just one click. You can create empty GameObjects, set positions to zero, rotate objects and add Kinematic, Drives, Sensors and other Game4automation components to GameObjects. The Quickedit overlay is changing the available functions based on the selected object(s).
