Laggy to DEATH
Mac OS: Excellent editor with good interface and simple usable design. It doesn’t overload you with too many tools - it just comes with what the majority of people need. HOWEVER: It is EXTREMELY laggy - almost unusably so. Performing any sort of action while working in a document causes the app to pause for a few seconds, showing the rainbow cursor. Actions that can trigger this include: scrolling, adding shapes, resizing objects, adding text, and changing format. This wastes a LOT of time. A real shame since this is otherwise a perfect PDF editor - and it’s 100% free.
