The most important thing I like about this product is its compatibility to many other softwares such as PHP and ASP.NET. This software also supports Linux OS and Windows operating systems. As you might know, it can run any web applications using JSP or Servlets. It's not easy to use but user friendly at all times. In my opinion nothing really because everything is good in terms of functionality. Maybe if there are better tutorials out there then maybe we will be able to see some new features added by them. We have used this platform for developing our own websites and mobile apps.
