im pretty sure, that the map will not be inside those tabbed pages! for one, i cant make out a suitable icon. then it would just make no sense, since theres no space for a good map in those little pages! i doubt that the inventory is in this tabbed structure too.
my guess would be that this is kind of characters list, each page houses another character sheet.
now we see "major skills" tab, than theres probably a "minor skills" tab, "race/class/name/reputation/bounty" tab, of course a "misc skills" tab and a "character attributes" (strength, intelligence, ecetera...) tab. this makes a total of 4 tabs "known", and theres only one more tab left, where i dont have a clue what it is on this screens.
inventory, map and characters have probably all different windows... i hope so at least

i like the compass, and how the indicator has been implemented. nice!
