Google Drive's Slides is now running with new features. editor
The first new feature is that slides now support widescreen presentations, and additionally, this format is the program's default.
The second feature is that you can customize the look and feel of an entire presentation based on a new “master” slide.
But let's analyze it a bit further …
Like Google Notes, widescreen displays have long been the default, and most devices and computer screens now come in widescreen format. It's only natural that presentations would also move to widescreen format, which is why all slides in Google Drive's Slides are now widescreen by default, although you can revert to the old format if you want.
As far as the second change in features is concerned, we can say that you now have the ability to customize fonts, colors and layouts for all pages by modifying only one, the master. However, individual slides can have specific formats if needed.
