Yay!   that works better but isn't the end all.   I experimented and, yes, the dot will restore the camera and director angles if the the previous scene had the dot set originally. 

I tried this.  I opened bryce and it opened my saved default as desired.  I added a different sky, changed a couple camera settings (dotting them as I went).  I changed the the infinite plane mat and saved the entire scene to a folder.  Now when I decide to start all over with a new project and select "new document" I get a blank scene with one infinite plane and sky.  Except the sky is that of the last scene saved and plane is the old out-of-box mat.  Also all of the camera dots of the previous scene is still there. 

Your advice is a help though.  I allows a quick way to reset the camera squared along the x,z axis which I prefer.
