I just received my book and I'm soooo happy!
After doing about 20 Blurb books, I’m convinced they are as good as anyone else, less expensive than anyone else, and BookSmart is the most versatile layout software short of InDesign. For Gourgandise and anyone who claims their pictures print darker, it’s likely because your monitor is not calibrated. Monitors from the factory have their brightness set too high, so pictures appear correctly bright on the screen, but in reality are not that bright. Most monitors are set to 180-200 (I think the unit is lumens). Try setting it back to around 100, and your prints and books will look like your screen.
removing pages from my book
I must be missing something. In my copy of Booksmart (v 18.104.22.168043, and previous versions) there is a thingie at the top of the page labeled "Remove Page’, right next to the "Add Page" thingie. It works fine. Is there an updated version where this button has been removed? Hitting the delete key will also delete a photo if one is selected instead of the entire page. Anyway, whatever is in the orange border goes away with the delete key.
