I just don't think it's a good idea. Reasonable people can disagree.
OK, you click on an airport then click hold. Then you decide to click on More Options. Is there another hold button? Where does it go when it times out? You click Search Nearby. Is there another hold button?
IFly allows us to navigate lots of different places and information. do they all time out? do they all have hold buttons.
I don't want IFly to attempt to become a mindless app that automatically does everything for me.
It would also divert resources away from other enhancements.
I think it's great to suggest enhancements and/or improvements, but don't expect everyone to embrace all of them or even most of them. A lot of it is an individual's vision of what this app should be.
