Hi, I think it would be good to add a 'RestoreTitleView. command.
It would restore the current viewport title view, if found in the NamedViews list (or even generic Top, Font, etc.)
Currently after modifying the original view angle we constantly need to restore it to evaluate the scene from the correct angle. That command would come handy as button/alias to quickly get back to original view without hard-coding the view names is macros, buttons etc.
It is scriptable now but seems like an essential need in core Rhino.
