The technique introduced here includes a uniform customization system, which can support the customization of multiple software applications simultaneously. Customization data of a software application can be developed separately from the development of the application. The customization data is then stored, via the uniform customization system, into a customization storage. When the software application is executed, the software application retrieves, from the storage, the values of the customization data via the uniform customization system. The uniform customization system outputs the retrieved customization data indicating the current working context of a user, which may be used by the user to locate customization options in a customization user interface of the software application, for customizing functions performed in the current working context.
