The Vertical Profile thingie is one of the best features of iFly (IMO) when you're flying VFR and trying to stay out of complicated airspace.
It would be even better if it automatically painted (or dropped) a marker on your destination airport, so you could easily tell in the mish mash of vertical airspace and the VP where you need to be.
For example, per my image (which is zoomed in so you can see better what I'm talking about)
my destination airport is shown by the blue diamond. Notice it's in the middle of the Class D airspace (which isn't always the case). But even knowing my destination is in the middle of Class D, it's something I have to imagine in my mind's eye while looking at the VP. Wouldn't it be better to mark it for me?
I'd like a marker as a minimum.
As a bonus, when the magenta line hits the top of the diamond (or perhaps the middle of the diamond), then you're on "glideslope" for arriving at pattern altitude. (Alternatively, the magenta line could be dashed, and then when you are on target GS, it turns solid.)
