Expert

Others have eluciated the most salient features of PDF Expert. Naturally, this amazing application is by far superior to anything else out there.

Two irritating issues:

Synchronisation with dropbox isn’t ideal, especially when using both the iPad + OS X version (I don’t use simultaneously + I allow time for synch). Often a duplicate is created.
The zoom using the touch pad is more often than not blurry. Entering a custom value renders a sharp image, using the touchpad does not. Perhaps these zoom values determined by the pad aren’t “rounded” to sharp ones?

Cheers
