I'm sure there's a simple way to do this but I haven't found it. I like to use Calendars for my Macs. They connect and update my MacPros, MacBookPro, iPad and iPhone. Very handy. But one thing I really need is the ability to delete an event or put a strikethrough line through it and have it archived to a DONE folder. I need to be able to see what has been DONE and when it was done, including any notes I have. Is this possible? Am I asking for too much? Is there a better application for this, that will also sync all Macs?
