A great and useful application – PDF Pro - Sign Documents, Fill Forms and Annotate PDFs Review

I usually annotate PDFs on my iPad, but there are times when I need to do it on my Mac. I have tried several apps like this on in the past, including Skim and others. 
PDF Expert does the job very well. 
I see another review saying it doesn't support Lion's Full Screen Mode; that's great! I don't want it, as it kills my second display. PDF Expert does have Full-Screen mode. Either click on the toolbar or press COMMAND-SHIFT-F.
The developers of this app are also adding new features and/or fixes with every new release, which is a good sign of an app that's here to stay.
I fully recommed it.
