1. A method for decomposition of cross-platform display, the method comprising: receiving data including information regarding a display screen of a host device, wherein execution of an application hosted at the host device opens a file and generates a view of content associated with the file in the host device display screen; and executing instructions stored in memory, wherein execution of instructions by a processor: identifies a plurality of different kinds of interface portions in the display screen of the host device, wherein each interface portion is associated with a command for the application hosted at the host device, determines a description for each kind of interface portion and for each of the identified interface portions in the host device display screen associated with each kind, maps each of the descriptions to an interface component usable by a client device that does not host a corresponding application, and generates instructions for the client device based on the mapped descriptions, wherein the different kinds of interface portions of the host device display screen are reconfigured into a single interface portion for the client device based on the mapped descriptions, and wherein commands for the application hosted at the host device and associated with the identified plurality of interface portions are grouped by kind and accessible at the client device via the single interface portion.
