Excellent But Annoying

At last - PDF Reader that is not as unbelievably slow as Adobe and has tabs (as opposed to the rest of the lot).
Looks excellent on Retina.
Upgraded from a version with "Find" keyboard shortcuts not working to a version with CONSTANT "upgrade" nagging.
Became unbearable, switched to FoxIt Reader.
Lowering the price wouldve convinced me to buy.
