The goal of this chapter is to show you how to present information to the user in ways that don't disrupt the current page. Pages use a View component, and render it directly on the screen. There are times, however, when there's important information that the user needs to see, but you don't necessarily want to kick them off of the current page.

You'll start by learning how to display important information. Knowing what important information is and when to use it, you'll see how to get user acknowledgement—both for error and success scenarios. Then, you'll implement passive notifications that show the user that something has happened. Finally, you'll implement modal views that show the user that something is happening in the background.
