I like the timer feature in SD and I've got one set to 30 min to remind me to switch fuel tanks. But the timer appears to start when I turn the unit on. It would be useful to have the option to set the timer to automatically start after takeoff (ie when the takeoff groundspeed is reached as with the flight timer). If you would also like this option please post here. Thank you.

I agree, but thought it already did work like the flight timer, I hadn't noticed that it started when you switch in on.
