Have a config item 'admin --> default user preferences' --> Task options --> task ordering ' to allow you to select default ordering options for comments that are posted. Even have a few icons on the frontend to temporarily change.
Minor code modification, but potentially a huge time saver as currently you have to scroll right to the bottom of the list to see the newest comments each time. Much better to have ability so newest comments are at the top of the list.
Thanks for considering!
