One small observation, though: your component is GPL, which means one can modify it as he/she wants and can distribute the modifications under the same terms. You cannot forbid them to modify a component unless they make a donation, this is not how it works.
Again, great job!
Congratulations to the developer, I am an extension developer myself and I very much like this one.
Keep up the good work!
By far the best content organizing component, it has everything that a website needs to get success. I haven't tested it yet for SEO but if that part is as well done as the rest of the component, than I cannot say something else but that I bow to the creator and wish them all the best in the world for giving the community their great work.
