You can navigate through the pages using your keyboard. Just tab down the messages to select ones you want to release, and hit return to submit the page. Or navigate down to the pagination box, where you can select a new page number by number, or using your arrow keys.
You can re-order the rows by clicking the header for the row you wish to move, then dragging it to your desired position.
Editing your columns to add "Caught By" will show the filter that caught your message. Messages discarded by your personal Email Filters will just show "filter".
