No good on El Capitan

iBooks Author is long overdue for an update. As many others have said, it slows to a crawl on El Capitan when opening files made in iBooks on earlier versions of OS X. The deal breaker for me is that my photos in the Photos app dont appear in iBooks Author’s Media browser, and there’s no way to drag and drop photos from the Photos app into an iBooks project. Get with it, Apple!
