Prefab Pick and Place lets you select prefab from scene view instead of drag and drop from project view.
Press hotkey to open the picker in scene view with a list of prefab from selected paths. You are not needed to use a large project view window anymore.
After selected a prefab from picker, you can move the mouse to change the position of the placement without holding the mouse button. In addition, you can scroll the mouse wheel to switch next or previous prefab before confirm the placement.
