At this time the XML viewer displays XML data pretty printed, but as soon as it is saved to an XML file the pretty print is lost and it turns into one long line. I believe that exporting XML data has the same result. My workaround is to put all the XML data in the clipboard and have Notepad++ save it as XML file and it saves the pretty printing. This workaround is not desirable as it is extra steps that should not be needed.

Please allow an option in the XML viewer (and exporting) to save/export XML data "pretty printed".
