When I first tried IB I was expecting the following:
That you could desing your entire interface and tie it together. So in the end you would have a 'visually' working application which you could show to your clients for their approval.
So this interface would work visually, but without any business logic tied to it *yet*. So it would exactly the same as it would be when it is finished: menu-items would work, preference-windows would work, new windows would open if applicable, only buttons would work that would do anything visually: opening new window, tabbing, whatever...
This would be really powerfull and usefull, any chance IB would support this in the near future?
