- If you hit "reply" and you meant "reply all" you can add the extra recipients with a single click.
- You can double click on a day in the calendar and create a reminder, appointment or meeting request. With Outlook if you're on the calendar I haven't found to create tasks, you have to go to Tasks first.
- You can save an email as a reminder or an appointment.
On the other hand I'm really appreciating:
- Integration with OneNote
- Decent italic font
- If you save a draft it doesn't just silently disappear into the Drafts folder, but shows as unread.
