Target Object

All adding a “Target Object” would do is:

• Create an Empty Object named “Target”
• Automatically add a “Track To” constraint to the camera and/or to the lights, (as selected by the user), which will use the "Target object" as its Target.
• Automatically set the correct “To” and “Up” values in the “Track To” constraint.

A mockup of the tool shelf. These would be the default values.

Additionally:

• By default, it will add the Track To constraint to the Active Camera,
• If the user has a single Object selected when they add the Target Object, the Target will automatically appear at its Median Point, and be parented to that Object.
• If the user has more than one Object selected, the Target Object will NOT be parented, and instead it will appear at the Median Point of all the objects.
• If no Object is selected, the Target Object will appear at the 3D Cursor.

Ideally, there would also be a way of going back and changing which cameras and lights target your Target, so that the user can change their mind later on, without having to add a new Target, or to manually add new Track To constraints.

The intended audience for this feature is not experienced users, but new users. It’s meant to make the first few hours in Blender feel more fun, by making the Track To system more discoverable. It also saves intermediate users from having to Google the correct Up and To values, or to remember the difference between “Clamp To” and “Track To”.
