Does OpenStack have a feature/plugin similar to Amazon CloudFormation Designer ? AWS CloudFormation Designer (Designer) is a graphic tool for creating, viewing, and modifying AWS CloudFormation templates. With Designer, you can diagram your template resources using a drag-and-drop interface, and then edit their details using the integrated JSON text editor. Does OpenStack have a similar feature/plugin to aid HOT template creation ?

NOTE: I understand that OpenStack Horizon has a feature for visualizing stack/template topology as a graph. What I am interested in is template creation.
