Thanks, Joe. I had already found those tutorials. They're quite good but I like to have a page open in a book because I find it easier to follow.
I definitely agree with that but I have a handy work around that accomplishes the same thing. I have the iBook open on my iPad Pro and work on my Mac or
vice versa depending on the app. The beauty of this is having the equivalent of a few hundred pounds of paper on a device weighing in at about 16 ounces. Not only that, but I can carry my references anywhere I go. I can and occasionally do use the iPhone the same way, but the larger screen of the iPad Pro is a lot easier to read.
