sort by sender
Sort by sender in New Mail is needed. It's available in folders, but not New Mail, which is where I like to filter things out. New Mail currently only allows to sort by date. I've had to create a new folder to put new mail into so I can sort it, but if I don't deal with it immediately it tends to get forgotten because it's not in the New Mail that I see each time I log in. Thank you!
Unified Inbox Style supports more sorting options.
