Since the build 2.0.2327, the sending audit is improved.
When an 'Update' action modifies the status attribute of an object, e.g. article, it gets displayed in the Audit palette as 'Send' action, followed by the original folder and the new folder.
The status attribute is the one configured in the schema as gs:stateAttr: for the article it is a folder, for the task it is the calendar and so on.
Have in mind that the history of sending was already available by navigating the XML with the StateHistory option:
Example:
http://localhost/gn4/do.ashx?cmd=objsNav&ids=3552&options=StateHistory
Result:
