The new layout is so different than the old that it is hampering my productivity. I thought Adobe was supposed to help users, not take away all the features that I need to see immediately when I open a PDF.
 Specifically, I need page numbers and the page up and down arrows front and center. I still don't know how to find those. I need to see at a glance if I have time to read a 5 page or 105 page document.
 Don't hamper users. Make it easy again.
 Allow users -- and tell us how to do this -- to return to the old layout: it was simple and uncluttered, and allowed me (and others) to easily read PDF files. You broke something that worked just fine the way it was. New isn't always better.
