Systems and methods for providing a collaborative document environment
Systems and methods are disclosed for providing a summary of suggested changes made to an electronic document. A suggested change is iteratively selected from a first list of suggested changes. A second list of modified suggested changes is generated by processing each selected suggested change in the first list of suggested changes. The processing comprises marking the selected suggested change for including or excluding the summary. If the selected suggested change is marked for including the summary, the processing further comprises at least one of combining the selected suggested change with a previously processed suggested change to form one of the modified suggested changes for including in the second list, and truncating the selected suggested change to form one of the modified suggested changes for including in the second list. The second list of modified suggested changes is provided as the summary of suggested changes.
