A very very small deal, but it still kills me a little inside. (especially because apple is so focused on the details that these things don't sneak through), but if you open a folder on the home screen, and double tap: the folder goes away but the page-shower-thing (the dots) pops up. This must be a bug, because it doesn't happen when a folder is not open.
