Oh. I thought it was a bug? What do you mean replaced by multitasking? If you're in Safari, I don't understand why can can't swipe to go forward?
Well if I swipe to go back in Safari but want to go back forward real quick (I'm often switching around a lot, testing websites, etc) I can't any more because the thing opens up the multitasking slideover window thing with another app. But that's the new gesture to get into split screen multitasking so I'm not sure what can be done except maybe a two finger swipe for browsing?
Are you talking about the 4-finger swipe to switch apps? If so, the direction has changed. It used to pull to the left and now it pulls to the right. Similar to the direction change for multitask. Maybe I misunderstood your comment though.
If you want the controls to show at the top of a browser just touch the browser bar. They will pop back into view. You could pull down quickly as well on the page but its easier to just touch the bar.
See above. As for controls, I just want a simple option to keep them always visible like we have for things like the bookmarks bar. It's just an annoyance, not a big deal. I can see hiding them on an iPhone but don't see the point on the iPad. I switch around between tabs a lot and it's annoying to do when they're always hidden by default.
