Systems and methods for applying both profile and user customizations to an application user interface are provided. Profile customizations, created for a specialized use or field, are adapted to an application user interface, which has command-menu-toolbar contributions from various add-in modules. The user has access to the customizations through a user interface. Then, as a user is customizing the application, through commands, toolbars, and menus, the user customizations are tagged. A priority and group is assigned to each customization to allow for relative positioning of each customization. The difference between the user's final desired state and a reset state is computed. This difference computation is used to track the changes made to the application and to assist in resets of the customizations.
