The ease of use and access to all information about my clients.
I can easily pull up any file or document with just one click! It's also very easy to create new files and folders as well as share them with other users/groups within our firm. Nothing so far really dislike but it would be nice if there was more customization options for your user profile page (you can't change your background color). We have been able to streamline many tasks from filing to billing which has allowed us to focus much better on what we do best - representing injured people.
