1. Organization feature for character saves. Every time I save with a different character it goes on a long list of saves without categorization. So hopefully there will be a way of categorizing saves that belong to the certain character.
2. The ability to have infinite save slots. I know Oblivion had it, Fallout 3 had it, so why not Skyrim. Fallout New Vegas has a disappointing and limiting 100 save slots so hopefully Skyrim can have infinite save slots as long as you have space on your HDD.
3. The ability to re-customize your face. Oblivion didn't have this feature, but Fallout 3 did when you had to talk the plastic surgeon, although if you killed him you would lose this feature (so probably have this feature not attached on an npc, much like a mirror you can go up to and change your facial features, oh yeah and have a way of resetting it to the face that you created initially in the beginning of the game, so all your work of 40min or so doesn't go to waste).
4. Character customization codes. People like to create and share so why not have a code so people can recreate the characters faces that others have made.
Most of these quirks and requests are simply for player flexibility and convenience and I hope Bethesda includes them in Skyrim.
