I would really like focus points for Nikon. The data is there and readily readable by other applications like ApolloOne. I would be willing to have the focus point burned on the preview for speed. I.e. to get rid of the focus points would require a full regeneration of preview images.
I say this as ApolloOne is quite slow to move between images compared to either FRV or Photo Mechanic. Speed (as you advertise) is important for sports photo sets.
