Camera Navigator is a Blender addon to make positioning camera easier. By using this addon, you can tweek your camera with the same keyboard and mouse setting as you positioning the viewport in Blender, but always keep the camera view, so that you can see exactly the preview of the camera. Without needing to work on the viewport and then align the camera to view agian and agian. This can you you a lot of time and be more accurate.
