I use between 6 and 9 windows in safari at any given time. There are 4 websites that I always have floating around in that 9, but not always in the same place. When you look at the windows all laid out next to each other they look like icons on your home screen. Looking at them you want to hold down on them and arrange them in the same way that you arrange app icons on the home screen, so that your "frequently used" sites are all up at the top and then random links that you're keeping around temporarily (like this thread that I'm starting) can be pushed to the bottom and then cleared out when newer things replace them, or rearranged as the importance of each changes based on whatever criteria. I feel like this would be even more important with an iPhone because you have to swipe through each page individually, but that interface doesn't suggest rearranging the way the iPad interface does. It looks like I SHOULD be able to rearrange them on the iPad. Anyway, I'm sure this has bothered someone else.
