The best features Alfresco offers in my experience include the intelligent search, because sometimes you need to find a document, and this solution provides a full-text search across different document types and formats, which is perhaps the most remarkable feature, along with version control. The solution tracks all the changes of the documents and prevents accidental overrides or other issues. The intelligent search has made my work easier because you can just put a word. Perhaps you are thinking of finding something related to a client or a specific MSA agreement, and with one or two words, the intelligent search proposes all the documents that include this word, facilitating finding the information very easily and very quickly. This is the most important feature for us.
