Components
Components are the building blocks of the software and represent a virtual implementation of a physical component such as a switch, rotary, LED etc.
Modules
Modules allow you to bundle Components together. E.g. you could create an aircraft lighting module consisting of a row of switches assigned to beacons, landing lights, panel lights etc.
Device Panels
Device Panels are what actually appears on your tablet and touch screen and are created by adding Modules. It is possible to create one large module that is the same size as the Device Panel allowing the creation of full size aircraft overhead panels.
Device Panel Groups
Device Panel Groups are an organised collection of Device Panels allowing the swiping in of Device Panels based on its position within the group. This means that a tablet is not constrained to display a single Device Panel during use.
