Here's some ideas and things I'd like to introduce next:

• Add an icon picker
• JSON Props Editor
• Allow displaying multiple variants of a component at once for enum props. All variants x sizes of a button for example.
• Add zoom controls
• Creating examples from the UI by saving the current state of a component.
• Generating visual tests based on examples and default properties for all components and visualizing changes in Compodium.
• Build and publish your playground
• Vue support

Feel free to share yours!
