Make the improved iPad top navigation more finger friendly.
I like the new top navigation bar which was implimented on the iPad very much. However, the icons are very small and the area around the icon appears to not be activated as beloning to the icon. This means that I am frequently turning the page back when I attempt to use the Back button to go to the previous passage I was in. Also, the back button itself is broken such that if you hold it down to select a particular passage from the history, if you then want to go back to the passage you were just on, you again have to hold it down to access the entire history because the Back button will not respond otherwise.
