MaGISTraTe, They're just to offset the inventory/magic menu's 3D item icon and the info card that's below it. Mainly for people with muliple-monitors.
The gift menu is the one you see when talking to that woman in helgen, when giving food/clothes to children (I think), and when planting stuff.
For the quantity menu limit, 0 disables it (I.e. E only takes/puts one item, apart from when taking weightless items, it takes them all [gold, for instance]) why would you need it as 999?
Someone could add a stats page, I don't see why not.
marrax, items with undefined values get pushed to the bottom of the list. e.g. sorting by weight, those with no weight get pushed to the bottom of the list, with the lightest item at the top, heaviest just before those with no weight. Otherwise you end up with a load of useless items before you get to ones with useful values.
The bottom bar button art is like that to distinguish between being able to equip to just your left hand or being able to equip to either. M1 E / E M1 M2 would look bad.
As for that scroll, I'll look in to it. Same sort of thing happened with that sailors thingy active effect, iirc.
