I registered for an account at SourceForge simply so I could leave a review of this software. It is absolutely the easiest way to preview your LUTs. Load an image, point the software at a directory where LUTs are stored, and it shows the image with every LUT applied. It does exactly what I wanted. Kudos to the developer. The only way to improve the program would be to enable a drag-and-drop feature so that you didn't have to navigate to the desired image/LUT directories. I've also donated to the developer. To encourage more software like this, I'd suggest you do the same.
