The most useful feature is the ability to use the same code base for different platforms. I can use one code base for a website and then easily move the code to another website without any issues. The code is very easy to use and the developer support is excellent. I haven't found any features that I dislike about the product. If you are looking for a simple CMS that will allow you to easily manage a website with one code base, then this is a great solution. The XOOPS CMS is a free open source content management system that allows you to create websites easily. From the website, you can easily add new content and edit existing content. The website can be accessed via a web browser or a smartphone. It's easy to use with many options available for customization and it does what you need done very well! The customer support team can be slow at times but they are always quick when answering questions or helping out if needed. I have had no issues using this product so far as everything works great. We were able to get our website up quickly after we purchased because of how simple it was set up and customized compared to other products that took much longer than expected.
