Gaia Sky provides a small location log feature that keeps track of the visited locations during a session. Currently, the location log is limited to 200 entries. Old entries are deleted as new ones come in.
The location log pane can be found in the control panel. Every entry in the location log has two actions available:
re-visits the location with the same camera and time setup as when it was first added: this sets the camera position, direction and up vectors to match exactly the ones at the time of the visit, and set the simulation time as well
instantly go to the object of this location
