I am currently trying to reduce my reliance on the backside display on my camera. All relevant information on the current frame are right inside the viewfinder, so taking the eye away from the finder to fiddle with controls is really unnecessary.
This works reasonably well for normal settings, but I quickly became annoyed with my own clumsiness with the two dials when selecting a new focus point (since there is that handy button next to the shutter).
So I wrote a little page that helps me practice the AF selection by providing me with a point grid and randomly selecting one point to manually change to while looking through the viewfinder.
