How to 'preview' app as my user would see?

[Breezy]

Hello, 

I have finished my draft app. I would like to see it as my 'user' would see it. How can I preview my app? I know that once an app is complete it often expands to take up more of the screen. Thus I need a 'preview' mode. I don't see that option anywhere though.

This is not true, 

When you are not in "Edit" mode, you are in user mode

I stand corrected!
