So far, so good

No reason not to give this five stars at this point. Dragged and dropped 12 .jpgs and it created a .pdf. Selected 3 .pdfs to combine and easily dragged them into the proper order. Still using Preview for most functions, but Preview is sometimes persnickety when it comes to combining .pdfs in the Thumbnail window. I suspect that this app will take over more than 50% of my .pdf chores and pass PDF Genius, as well, for my tougher tasks.
