Add a Fullscreen Button in the Program Monitor.
I'm honestly still surprised that even the latest versions of Premiere Pro CC still doesn't have this feature, Premiere Pro CC really at some point needs to add a Fullscreen Button both in your Computer's Drop Down File Menu and in the Program Monitor so you can actually playback all of your assembled video and audio clips in Fullscreen mode, and then obviously press "Esc" to exit out of Fullscreen mode.
I'm aware that you can use the ~ (Tilda) Key to closely zoom in and maximize the length of each window in each tab which I have used, but I want to be able to do a close analysis of assembled video by watching a Fullscreen video preview to do so.
I honestly thought the Premiere Pro Development Team would of added Fullscreen mode in future versions of Premiere Pro years ago, but now it's 2020 and Final Cut Pro 7, 10 and tons of video editing software have had Fullscreen mode for years, so I still don't understand why the team still never thought of adding a Fullscreen button if it was just an oversight by them.
To me this seems like a no-brainer. I hope that fullscreen mode gets added soon at some point in an update because this is such a basic feature that really should of been added years ago because it'll be very helpful to closely analyze a preview of your assembled footage before you export it.
We have had this feature for many years – Ctrl+Tilde. Esc to get out. I know we have a lot of keyboard shortcuts and you aren’t expected to know them all, but one good way to find out what they are is to open the Keyboard Shortcuts editor from the Premiere Pro menu. From there try searching for commands to see what the shortcut is or even reassign it to something that makes more sense to you. Hope this helps.

@Francis Crossman, Well I'm glad that the team has had this feature for many years, I'm disappointed that this is an exclusive keyboard shortcut because I haven't mastered Premiere Pro to that kind of professional level since I don't really use Keyboard Shortcuts that often. This fullscreen feature needs to be expanded by adding a Fullscreen command under the Application Menu under [View – Fullscreen] so you can also toggle fullscreen mode from the drop down menu, and I also think it should be added as a button under the Program Monitor's Button Editor so you can also toggle Fullscreen from the Program Monitor to make it a bit more user friendly towards beginners since Final Cut Pro has had those options and commands for years now.
Keyboard shortcuts are nice and are powerful tools but not everyone will remember those shortcuts, this is in order to make the app more user friendly towards beginners and intermediate users. That's all.
Tilde = maximize current panel.
Ctrl-Tilde = full screen.
