The ability to work on the same content from multiple locations, and have that content update in real time. We also like the ability to have multiple authors on the same page, and have all the comments and edits update in real time. The tool is sometimes buggy, and sometimes works well, but the team is constantly working to improve it. There are so many features that are important to us, but not all are supported in the current version. We hope to have them added in the future. We have multiple editors working on content for multiple clients. We are able to work on the same content at the same time, and have it update in real time. The best thing about this is that it has all the features of a traditional CMS like WordPress. It also has a drag-and-drop editor which makes things easy for non-technical people. Although it's not free, I think the price is fair considering how much you get. There are some bugs here and there but nothing major. I would recommend giving it a try if you're looking for a good CMS solution. We have been using this as our CMS since we started building our website. It has made things so much easier for us.
