Lots of design philosophies out there.* Sometimes it's good to
   hide things under multiple screens.* Sometimes having things
   "pop up" or "slide out" is good.* Othertimes it's good to have
   everything available in a single screen. Maybe prioritize?* What
   functions will be used most often?* What information will be
   needed most often? Ask questions like, "What's the least they
   need to do this?"* and make that first (if multiple screen) or
   highlighted (if single screen) - like surrounded by a box, or
   different background color. In fact, if this is console/native
   font... make full use of background colors as that will help
   speed/memory retention. That's just a few thoughts.*** I know
   there's some cognitive things, like "the human brain can process
   7 distinct things* plus or minus 3 ,at a time... so many times
   menus or displays have a maximum of 7 items in them. Also, I'd
   look at competition.* You can learn a lot from what they do
   right, what they do wrong, etc.
