the unique navigation for giving thanks

wondering what you think of this overlay style nav. there's not always a need for the normal bottom bar. an app like this could get away with something different.

notice the dots up top. 3 sections that you can just slide back/forth to just like on the iPhone homepage. your thanks, everyone's thanks and quotes. the rest you can get in the left top nav item.

thoughts?
