I just updated to Mavericks and updated iMovie and I don't like it at all. All my projects were all moved around and it took me a half hour just to figure out where everything went. Then, I find that the function to put chapters in between clips had disappeared. Then I realize I can't even share the project to iDvd so that I can burn it to disc. That's horrible! why take away features when finally updating iMovie? Not everyone has gone digital and I need to burn discs for my employer so that he can send them out. I used to make chapters and a nice DVD menu that worked great for the company. Now I can't do any of that? Epic Fail!!
