A slider bar in-game (hehe, unloving sponge attack) would be nice.

With option templates such as Very Low, Low, Medium, High, Very High, Ultra High, and Custom. You can use one of these as your template and then make modifications. Players can quickly determine whether one of the templates works for them without having to take a screenshot, leave the game, make an adjustment, log in, load back into the game, new screenshot, etc.
