I think it would be useful if there was an optional confirmation dialog when editing the data of an allready saved QSO, just like the Delete entry confirmation dialog.
It is a little bit "dangerous" to alert the data of a QSO by accident.
Maybe a notification when clicking the FIRST,PREVIOUS,END,NEXT,LAST buttons that the "data has changed, save changes?".
