I would like to be able to pin a folder in the Thunderbird Folder Pane so that it always shows even with no unread messages in it. Right now I have to mark a message as unread to keep the folder showing in the Folder Pane.
Right now if a new message arrives in a thread it is not obvious there is a new message. When a new message arrives in a thread the thread should automatically expand to show the highlighted new message.
