Best Practice question (or is this a doh! kind of question...): 

I'm modifying Record Page layouts to remove the News Tab (wish there was  Tab Visibility ability), but I would like to be able to see the "baseline" system default version easily.  Is there a suggested best practice to be able to  "see" the system default Record Page layout?  Or is the only way to see the system default version is to deactivate the current Record Page layout?
