You can change the Auto Correction options in the Levels or Curves dialog box by clicking on the Options button. There are three options to choose from: Enhance Monochromatic Contrast makes the highlights lighter and the shadows darker; Enhance per Channel Contrast produces a more dramatic correction and changes color castes; Find Light and Dark Colours finds the average lightest and darkest pixels and uses them to maximise contrast. You can select any of these as a default algorithm for all colour adjustments.
Palettes and moveable dialog boxes are always saved in the same place in Photoshop whenever the application is quit.
