I'm very pleased with Preview's annotation capabilities and the fact that colleagues can view my annotations using Acrobat Reader on their Windows machines. However, most of the pdf's I read and annotate have figures on one page and the description of the figures on separate pages. I would like to be able to read the text description (in one window) while also viewing the figure (in a second window). For example, in Word or OpenOffice, two windows for the same document can be opened under the "Window" menu and selecting "New Window". I don't believe Preview has this capability. I thought about having two copies of every pdf to do this, but this is not a very elegant solution. Mac solutions should be elegant, right? Any thoughts on how I can accomplish this would be greatly appreciated.
