How do I show the rich layout editor in Android Studio? [closed]

Question

How do I show or use the rich layout editor talked about in Android Studio?

More Info
I'm new to Java and I just downloaded Android Studio and created the Login example. I can't seem to find the "rich layout editor" that is in the brochure. I want to create an app and layout the UI components. I'm trying to learn code by looking at the code that is generated by the rich layout editor.

More Info
Android Studio - A rich layout editor that allows you to drag-and-drop UI components, preview layouts on multiple screen configurations, and much more.

I figured it out. To show the rich layout tool you have to open the file in the layout directory, "src/main/res/layout". For me this file is, "login.xml".

Also, note that at the bottom of the screen are two tabs, "Design" and "Text".
