Well, I didn't like Clippy and I can understand the point of some users (about too many boxes popping up - already I mindlessly close the window that pops up about my GPS not working. If we had more than one pop up, they would start to get confusing. (They might need to be color coded or something so as to distinguish one from another)), I still like the idea of auto-reverse.
I mean, if you're "destinated," your last (and still current) flight plan doesn't make any sense. You can't fly from your starting point to the destination that you're already at. And once you're "destinated," you have to make one of three choices on the Flight Plan page next.
You're either going to go back home, which I'm guessing 80% of us do; or you're going on to leg 2 (guess 19%); or you're going to cancel the flight plan and stay local for some sight seeing. (The last 1%.) Whichever, you have to interact with the FP page. (Unless once "destinated," iFly automatically cleared your Flight Plan. That would be interesting, but a pain for the 80% who simply reverse their last flight plan to go home.)
But I agree that it's easy enough to just go to the Flight Plan page and tap the Reverse button. Only two taps. If iFly were to pop asking if you wanted to reverse your Flight Plan, that's one click. Not much of a saving.
