Planned features:
  • Replace the default PalmOS brightness dialog.
  • Turn off backlight with a check box.
  • Definition of brightness profiles.
  • Dim backlight after a period of inactivity.
The difference to the default PalmOS brightness is, that SilkDimmer is able to turn off the backlight.

  • Zire 71
