I like the fact that I can use the plugin framework with my existing APEX applications. It is easy to use and I can use the same code base to build both the front end and the back end. I dislike that the plugin framework is not supported by the Oracle APEX team. I have had to build my own custom code to integrate with the plugin framework. This is a problem because I am not a developer. I have to work with a developer to build my custom code. I have to integrate with the plugin framework to build applications that are not supported by the plugin framework. I am solving the problem of not having access to the APEX framework when building applications that require a custom front end.
