Claim:
A method of operating a data processing system comprising: the data processing system running a source code editor; displaying a source code of a project in a graphical interface of the source code editor; displaying at least one cross-reference marker, the at least one cross-reference marker indicating crosscutting in the source code; receiving an input to change the source code; the data processing system determining if a new project build is required; in response to determining a new project build is required, building the project; changing at least one cross-reference marker in response to receiving the input to change the source code; highlighting the at least one changed cross-reference marker, and including with the highlighting a symbol that enables tracking of a type of change being highlighted by the highlighting, wherein the symbol provides an indication whether the at least one changed cross-reference marker is an addition or deletion, wherein a plus symbol is used to indicate the addition of a new cross-reference marker and a minus symbol is used to indicate the deletion of a cross-reference marker; determining whether there is an existing map of crosscutting in the source code; and in response to determining an existing map exists, saving the existing map as a prior map.
