Simple request - Allow the creation of a "group", and the creation of abilities or attributes inside that group (or drag & drop between them). Allow groups to be expanded / collapsed to make managing the character sheet easier. Bonus: For any groups created, include a navigation menu or quick-jump list on the left hand side, or at the top of the sheet, that creates anchored links to get to the group quickly. I know the character sheet isn't meant to be totally comprehensive and full of data to manage, but once you have to start scrolling and looking beyond even a full page on a laptop screen... it gets cumbersome :)
