Currently wasp-os enables a narrow set of applications because we don't want to consume RAM by importing the module and constructing the application. We can improve on this situation by providing a small (stateless) application that can be used to enable or diable applications. This allows all the ROMed applications to be enabled using the GUI without compromising on the ability to develop applications. In fact this application significantlly reduces the RAM consumed in the default case becasue the Self Test app does not need to maintain its state.
