Even though many current prototyping tools tend to see an application as a bunch of views, we all know that a real application is not made only of a set of mere visual assets.
While building a cross-platform application, you obviously wish your visual application framework (FMX in the case) to deal with visual aspects but at the same time, to provide actual functionalities. This is because you will end up needing some level of interaction with the platform your application is running on.
Modern applications have to provide advanced functionalities, including some that are really basic (not always trivial, though), such as (multi-)touch support, and interaction with the system clipboard or with the filesystem. There are some possibly more specific topics, such as sensor integration (camera and positioning, for example), or other device-/platform-specifics such as notification systems, voice recognition, text-to-speech, and other advanced capabilities.
