Camera to behave as the viewport? One of the things I haven't learned about using Blender is how look from a camera and use the exact same commands to pan, rotate and zoom with the camera as I do with the viewport. I'm used to doing this with either C4D, Maya, Modo, Max, etc... but in Blender It feels like a different workflow for those who are coming from other 3D applications. Is there anything that can be done about this either in the settings or through an addon?
Enable "Lock camera to view". Then all navigation in the viewport will be done through the camera using the same commands as navigating on any other view in the viewport.

In 2.8+, you can access the checkbox in the right side panel in the 3D viewport with N :
