.Not being able to crouch with an arrow drawn. You could in oblivion, it just feels clunky not being able to.
.Be able to jump whilst sprinting.
.Remove the long delay when switching from bow to drawing a sword when both are hotkeyed to the left/right d-pad.
.Why does the camera pan out when I draw my weapon in 3rd person? keep the distance fixed, if the player wants to pan out, then let them.
.Enable a toggle for auto brightness adjust mid game.
.Enable a toggle for 3rd person finishers.
What would you fix?

Camera switches to combat FOV I guess? Never had problems with brightness. You wanted to turn off finishers? I think they are really cool.
