Finding myself in a bit of a document handling app crisis like now since I'm not really happy with either of the three above. Goodreader is the one I use, simply because it has a zoom box feature for hand written annotations, which is an absolute requirement for me. PDF Expert has some ****** "innovative" (read: useless) zoom feature, whereas iAnnotate - which is the app I like the most in most other respects - doesn't have anything. So, what I'm wondering is if there's any other apps like the three above out there? Note that I'm not asking about note taking apps like Good Notes/Noteshelf/Notes Plus/etc, only apps that are first and foremost document reading apps with annotation features, not note taking apps with document reading features.
