Along with these screenshots, you can see the following menu items:

  • Friends list
  • Miiverse
  • Nintendo eShop
  • Internet browser
  • Nintendo TVii
  • Download management
  • Controller settings
  • Close software
  • Instruction manual
The ‘download management’ option is very intriguing.  Perhaps this will allow you to pause/continue multiple downloads for Wii U while playing games.
