Auto-Spotlight in Outliner is an addon for Blender’s Outliner that was developed in response to a request by a member of the Blender group. It streamlines your workflow by routinely increasing the Outliner to point out the chosen object everytime you click on on it within the 3DView.
Whereas Blender does have a button to develop the Outliner to point out the chosen object, it requires an additional button press every time. With the Auto-Spotlight in Outliner addon, this course of is automated, saving you effort and time in navigating a big scene with many objects.
