If you logged into your Google Slides today, you may have noticed a new option in the "view" drop-down menu. Where there used to be a "master" option there is now a "theme builder" option. This change is purely cosmetic because nothing else changed. The functions of "theme builder" are exactly the same as "master view." The announcement from Google said that this change was made to better communicate what that setting is for and to eliminate a non-inclusive term from the menu.
