Notifications were added to the Approvals app. New approvals will show as a typical notification in the upper right corner in Windows 8. This is similar to receiving an email or calendar notification.
Notifications from the Approvals app can be turned off within the PC Settings area like other Windows Store apps which are installed.
Guest and Gift features were added to the Expenses app edit experience. This enables adding guests (name, company and title) for categories like meals or entertainment. It also enables adding gift recipients and amounts for the gifts category. Guest and gift recipients can also be (multi-) selected from the Windows 8 People app. This is enabled by selecting the people icon when adding a new guest.
