Just like Preview and Acrobat, having the file displayed as contiguous pages without having to click Next and Previous would be a nice feature. If not possible, then a key-combo to follow the Next (not previously visited, of course) link would be nice. In either case, minimizing the use of mouse clicks is the goal. Also if neither is possible, could the Up-Down arrows be activated as a default for new pages. I find it a bit awkward having to click on the page just to scroll down after I click the Next or Previous link.
Thanks, you're done a great job already.
