I made some tweaks to the css for my taste, simply deleting everything in "#slides" cleaned it up. I also ran into a few issues using using MAMP for development where the slideshow was trying to display the Mac's .DS_Store file and that messed up the frame size and displayed a blank slide. It would be nice if invisible files were ignored. But overall it's still worth 5 stars to me.
I find all software can have small problems occasionally. What matters at that point is service and in this case the service was excellent.
The regenerate all tags function is nice but I would like that if instead of rewriting all the tags on the website it could be limited to just certain categories or only empty tags. Even without that I'll give it 5 stars.
I had an issue which ultimately turned out to be my bad but the help was quick, thorough and fixed in just a few posts on the support forum with the developer.
Highly recommended if you don't need a full store.
