I added the strings just last night, so unless there is some hyperactive Spanish translator out there, they haven't been translated yet

The setting binds your custom values to the restore button. So whenever you press the restore button (which is in the menu for adjusting the custom view), it restores contrast and brightness to PRS+ settings, instead of to 0 or prestored values. I tried experimenting with different approaches to avoid having to use the restore button, but couldn't make it work without breaking the builtin functionality.
As for adding more values: that shouldn't be a problem. Ideal would be if users got a popup where they could enter the value themselves, but I'm not sure PRS+ supports such a dialog in the settings menu. Kartu will know the answer to that.
