I've got a few suggestions (not sure how useful/realistic):
1) Sorting items by value/weight. I rarely care what items are heaviest; I am much more likely to care about lbs. per gp value when deciding what to carry around.
2) A dead feat bonus. Like if you choose a class that gives you Martial Weapons and Medium Armor Proficiency and you are a Shield Dwarf, you get some little bonus.
3) If a creature doesn't know what to do on its turn after it has been attacked, have it run toward last known location of attacker, run behind cover compared to where the attack came from, or run in a random direction (better than standing still).
4) Have all characters enter combat at the same time. Have combat end if NPCs cannot detect characters for a certain number of rounds.
5) Proficiency (or expertise) in an INT-based skill per INT bonus. I mean, INT really sucks right now.
