After using the free version for an evening, I popped for the pro version.

I found this to be a terrific addition to my media library toolkit as it provides good options for categorizing images. This is helpful when I’ve uploaded dozens of images and categorized them, and I’m ready to create topic-based sliders or galleries. I can now easily select a category, then choose images within that category without scrolling through 100’s of unrelated images.

The developer is responsive and helful to questions.
