The goal of the story is to create a form browser so that the user can select existing forms from it.
One use case of this is related to tracking actions in Audience Targeting (https://issues.liferay.com/browse/WCM-593), as follows:
- The user creates a form and wants to track user interaction with that specific form
- After creating a campaign and user segment in Audience Targeting, he/she creates a new report
- The user selects "Form" in order to track it
- The user then selects the form that he/she wants to track from the list of available forms that show up in the form browser
