So I assume you figured out how to delete unnecessary screens. So while in the edit screen mode (where you see the multiple screens and have the ability to add or delete screens), to make a different screen the "home" screen, touch the menu capacitive button. You'll then see "Set as Home" banner just above the capacitive buttons (this is where the "Remove" trash can icon used to be). Touch "Set as Home", then select/touch which screen you want to make the new Home screen, then touch "Done" down below. You should then see the little house icon on the screen you selected.
