Any time a form is created, a default View is created. This View contains all form fields, it's set to 10 submissions per page (or whatever value you've entered in the Settings -> Main page), it orders the listings by submission date - most recent first, and is publicly accessible by all clients.
Normally, when adding a new View, you'll see a dialog window appear that looks something like the screenshot to your right. This is extremely powerful: it lets you create a new View with all the fields, no fields, or base it on an existing View. If you find yourself needing to create multiple, similar Views, this can be a very important time-saver.
