5. Do I need to modify the System Code? 

Although platforms today should be “open” for external integration- there shouldn’t really be a need for you to have to change the code yourself. However, should there be the ability to control the display later? Most definitely yes. In the future, the system code of content management platforms will be upgraded by professionals without the need of the end user to do anything. The paradigm of upgrading your platform will be a thing of the past, new features will become available for use as they are developed and the need to “rebuild” or “upgrade” will be gone.
