A method, computer program product, and system for a quality-of-service history database is described. A first input associated with a change to a component of a graphical user interface is received, wherein a portion of the component is represented as a first node of a tree structure representing a portion of the graphical user interface. A first characteristic of the change is determined. The first characteristic of the change is associated with a second node of the topic tree structure. The associated first characteristic is transmitted to a first computing device, wherein transmission of the associated first characteristic allows one or more of the first computing device and a second computing device to determine a first aspect of the change based upon, at least in part, the topic tree structure.
