1. A method of reconfiguring an application graphical user interface (GUI), the method comprising: receiving, by one or more processors, a description of a layout of an operating system (OS) GUI for an OS, wherein the OS supports an application, and wherein the layout of the OS GUI identifies positions of representations of OS features that are displayed on the OS GUI; mapping, by one or more processors, the OS features to application features of the application that is supported by the OS, wherein said mapping establishes a relationship of application tool icons to the application to be equivalent to a relationship of program icons to the OS, and wherein said application tool icons represent functions that are provided by the application; reformatting, by one or more processors, an original layout of an application GUI for the application to mirror an appearance of the OS GUI, wherein representations of the application features are displayed in a same relative position on a reformatted application GUI as representations of mapped-to OS features on the OS GUI; determining, by one or more processors, a past frequency of use of the application by a user; and in response to determining that the past frequency of use by the user exceeds a predefined level, reconfiguring, by one or more processors, the application GUI back to the original layout of the application GUI.
