I like expansion. There is practical benefit, able to derive the rating of the best articles from one or several categories. When using the articles of several categories you will be displayed with great articles rating, regardless of the category. Multi-language support, works well on the site and in the admin (my website uses 3 languages). Setting is standard, the files for different versions of joomla are in the general archive (remember to unzip it). Very pleased with the technical support, the author helps to solve the problem, if there is one. In my case it took to give access to the admin area and to databases.
