I was just about ready to post a screenshot showing how there is now the option to save the "Now" Layout, but then I noticed a couple bugs.

1. The "pencil" is there, but when I click and name the layout, it does not move to the Saved Layouts side.
2. In my example, I saved the layout when the desktop was empty and called it "Close All". However, when I opened a book, the "Now" layout keeps the "Close All" name I assigned but it reflects the current layout and not the blank layout condition in which it was saved.
Boy I hope that makes sense.
