Under species view if I'd like to be able to list birds by date of sighting. Then I can easily determine if I just seen a bird for the first time this year or the first time ever etc. ......or in reverse order so I can easily see when was the last time I saw a particular bird. Perhaps by clicking on "Last sighting" or First sighting" the list could be displayed in ascending or descending chronological order.. (May also need an option to restore the users default order or alphabetical or taxonomic)
