I was thinking that Apple should let us have multiple docks that we use in our multiple spaces. So in one "Space" you could have a "work dock" which has all your applications for school or work such as Safari, iWork/MS Office. Then in another "space" you could have a dock for "Play dock" which has iTunes, Safari, iChat, Photo Booth, iLife or any computer games you have on your Mac. What do you think? Yes? No? It would be completely optional, of course.
