I wish Apple would introduce Application Groups (like tabbed pages) so that I can classify my apps into groups and display just my Games, or Utilities, or News applications etc.
Having the capability to arrange the icons in iTunes is good, but it is still a flat-file implementation. So, if I add a new game, which is on my 3rd page (of total 8 pages) then I have to move it from the 8th page to the 3rd page and cascade all the icons from pages 3-8 etc.
Messy.
