- Added an Export Preferences… button in the Preferences view to save a copy of the preferences to a file. - Added an Import Preferences… button to load a saved preferences file and replace the prefs. - Added a document type and UTI type for the prefs file (you can provide an icon if you like). - Enabled iCloud document support to allow saving to shared locations. - Added a bridging header to enable Swift code to work properly.
