I am creating a huge site for a hospitality & tourism business. There are tons of categories and I very grateful to have this extension because I NEED it. Tried others, this was THE best!.. One suggestion that I do have is that you add the ability to be able to assign a sub category to multiple parent categories. I have to individually add in restaurants, bars, etc to each city for each province/state for each country. Its going to be a lot of work. If there IS a way to do this I apologize and would appreciate some direction, if not, I hope you can add that in for uses in the future.
