Hi all,
We are glad to announce that we have just released the Paragon Playground, a beta version that allows the following:
- see in real-time how the components interact with each other
- copy the components set you have done and share it with your team
- preview components in both Open edX and edx.org theme
- this tool is good cooperation for developers and designers working together
Your feedback is important! 
Please leave your comments and let us know if it is helpful for the development.
