Simple console tool for saving and restoring display arrangement on OS X.
For doing it, the tool uses serial numbers for the displays and not the IDs that OS X assigns to them.
da help - prints help text
da list - prints a list of all connected screens
da save <path_to_plist> - saves current display arrangement to file
da load <path_to_plist> - loads display arrangement from file
If <path_to_plist> is not specified - the default is used: '~/Desktop/ScreenArrangement.plist'
Currently this program does not support Y-axis arrangement due to author's laziness. It will arrange all window on the same Y-coordinate. If you want to fix it, feel free to make a pull-request!
