NOTE: Also consider the new ButtonBar extension.

Dan Howell and GravityLab have made available an advanced Flow Navigation Button with no fewer than 12 built-in features, including:
- Add bespoke navigation options in a flow. For example, replace the “Next” button with a “Save and View” button.
- Launch new record or edit page. For example, launch the create new account page with a specific record type.
- Auto launch a quick action. For example, automatically launch the new opportunity quick action when an account with the type “prospect” is created.
- Navigate to another page. For example, auto navigate to another record page when a certain status is reached.
