I upgraded today and it works great! I have about the same time between different screens as the others; around 5 seconds. You added a lot more screens in addition to the buttons. Very nice.
Question - when the GPS mode is on, does the position get saved in the .ini file? I was thinking of turning GPS to on, connecting to my bluetooth GPS to set the location and time, then turning GPS off. Would it slow things down to leave GPS set to on?

Also, are civil, nautical and astronomical twilights listed anywhere? I know they're shown on the bar and circle graphs but I don't see the times listed anywhere.

Thanks for a great app!
