> I say that navigation state should be in the URL. That's a truism. You still have to decide what navigation is. - opening or closing a modal - switching between representations (example: grid view vs list view) - collapsing / hiding major parts of the screen - entering something into a search box - turning knobs on a form that draws a graph - drag and drop ui elements without side effects on the wider application - the above with side effects on the wider application All of these things and more have been implemented with or without changing the URL.
