• Add single instance TinyMCE prototype that has the same UI as the mock-ups.
• Add another "playground" prototype where it's easy for me to experiment further. (People could add more playgrounds, feel free to suggest better alternatives.)
• Make sure components are reusable (sure as text patterns, cleaning paste...) How to best do this? Shared directory? Hot-link from somewhere else?
