I tend to keep a lot of PDF files in Evernote. I usually end up viewing them using Acrobat, b/c the Evernote PDF viewing capabilities are limited. Here are a few quick suggestions for some simple improvements that would make viewing PDF files a lot easier. Improve navigation between pages Moving between pages is awkward. You have to hit the arrows in the grey pop up window that says "Page 1 of 4593 pages" (uh, I have some seriously large PDF files) Make the PageUp and PageDown keys move one page backwards and forwards, respectively (as in Acrobat)Make the Mouse scroll button not only move within a page, but automatically scroll to the previous and subsequent pages (as in Acrobat)Include right side document scroll bar to allow "jumping" to other sections that might be hundreds or thousands of pages away (as in Acrobat)Zoom function It would be great to easy ways to zoom in and out when viewing a PDF. Use the CTRL-Scroll button to zoom in and out (as in Acrobat)Have buttons at top of note window that allow you to zoom the page to (1) fit entirely in the window, (2) fit horizontally, (3) fit vertically. These buttons might be useful for viewing other types of documents.Document Navigational Links Although links to external webpages work properly, the PDF links to internal pages don't work. The big area where this hurts is with the Table of Contents. Many documents have table of contents that are linked to chapters or headings inside the document. If you want to get to, say, the table on page 1282 of a document, it would be a lot easier to click on the link in the Table of Contents than it would be to hit the forward button 1281 times. Thanks for all the great work that's gone into Evernote. You don't know how encouraging it is to see the steady stream of small improvements!
