With 5-6 screens of my menus options, I full use these.
Here are some of my setting
format
battery
Speedllite control
MLU
# bracketed shots
ISO speed settings (for auto ISO)
long ex noise reduction
High iso NR
GPS settings
Date/time
Image copy
LCD brightness
sensor cleaning
record function
custom shooting modes
Viewfinder display
As I get to screen 3 most of the setting are rarely used but easier to find them here than in the menu structure
