I moved the apps out of the folder onto the dock. Then when all the apps are out the folder disappears.
You don't have to move them to the dock.. Just move them to the black X in the upper left of folder view and they end up back in the higher level folder.
When you do this to the last icon in the folder, the folder goes away..
I was a little hesitant to delete the folder in case the apps got deleted. Dragging them to the X seemed to work. It just took a bit to find exactly where to drag to so it would move back to the home screen.
you can create new blank pages too just move an app over to a new page and blank page gets created...you can also have more than 3 icons on the favorites at the top
