Currently, System pages default template to _cms_default_blank_template
Recommended change: Change default template to Use Default Template
And then just make the _cms_default_blank_template default on new trial sites.
This way when adjusting all the system pages… its a matter of setting the default template to whatever we want… rather than having to go through each one and changing it over.
Like I said… Low Priority for bottom of the backlog.
