twitter app #1: back button goes one step at a time, up until the "tab" you started in
twitter app #2: back button just goes back to the tab you started, no steps
twitter app #3: back button goes one step at a time, does not stop at the last tab, keeps switching to the tabs you were at before

twitter app #4: back button literally reverses time
