Cons
Con Deadly slow on complex pdf files
Con File information missing page size
Con No multiple mapping of commands
For example:
moveDown=Down
moveLeft=Shift+Left
moveRight=Shift+Right
moveUp=Up
Having two key mappings to execute the moveUp command doesn't seem to be possible.
Con Configuration intended via GUI
There is no explicit documentation of configuration parameters used in qpdfview.conf and shortcuts.conf (those are the most important ones). However the files are editable conveniently, which is of value.
Con No Distribution version of the installer
Adobe only provide exe files and do not provide an msi installer for bulk deployment
Con Lack of support
Adobe support openly admitted to not supporting the product and recommend the use of forums.
