What is the most convenient way to disconnect and re-connect with iPad?

If you are currently connected remotely to a computer and want to break the connection, simply press your iPad's Home button to quickly disconnect the Splashtop Streamer connection and display the iPad's Home screen.

To easily connect to a computer, tap the Splashtop Whiteboard icon  in your iPad's Home screen, then tap the desired computer name in the list.  It's even faster if you have already configured its security code so that you do not have to type it in every time.
