It would be very useful to allow reporting on tracked changes. At the moment, the only way to actually identify changes is to actually going to the file in Webeditor.
In order to monitor the changes and establish patterns to action on and improve the base text (either at customer review, or even edting after translation), it would be very useful to be able to have reports (even excel with data dumped ie csv) with customer, project, file name, source and target lang, user, content prior change, content after change, date change. This will allow to mornitor who changed what when, relate it to customer and key variables such is language combination.
