The inventory sort appears to be sorting by type of item, and then alphabetically within the type.
The Equip window only displays items that can be used in the slot. Very nice!
You can drag them to another position on the screen, and stretch horizontally.
Might be my imagination, but it FEELS like crafting SP is coming faster. I haven't done any combat or grouping, so I can't speak to those changes, but I'm looking forward to being able to heal by selecting group members from the group list.
In general, everything is a lot faster and more streamlined. I'm liking it a lot.
