1) Make 1st row in the CSV a fixed header. When I sort the table on the plugin interface, it sorts the header too which makes it time consuming to upload the CSV again or swap the rows.
2) Hide column/row (Just to check whether the table looks better/worse without a specific column or row)
3) Multiple file import
4) Re-import onto the same table (update csv files and all that)
Thanks for listening. It's a really good plugin which I'll use on all my WP sites :)
