You can click on the links in the column to filter your view; in this screenshot, clicking on "Swap" in the "Exchange Types" link will filter the list so it only displays seed swaps. You can also sort the list according to the Quantity, Seed Expiry Date, or Exchange Expiry Date by clicking on those column headers.
