I would like to see when a file is exported that the header information of what each column contains is included.  Exporting the data, locating the correct template file, and then pasting the data into that file just to make sure you don't edit the wrong column is a great waste of time.  Also, as the columns change with each software version, there would be no doubt if you are using an outdated template file.

If the import function could be re-written to accept the first row as a header without forcing us to strip them back off, that would be an added bonus.
