I've just setup a new Blog for a friend and thought it's better to not give him Administrator Access right away as a precaution.
I created a new user as Editor therefore.
But then I saw that this user can not change the Theme Settings like Background and Header.
Is there an easy way to allow the Editor Role to edit any theme settings in Twenty Ten or a Child of it? He should basically be able to do anything an Administrator can do reg. the Theme, probably even changing themes.
