We have seen previous slides showing off how RIM is planning on differentiating “Toasts” on BlackBerry 10. In case you don’t know “Toasts” usually refer to simple notifications in a small popup that usually goes away. In BlackBerry 10 RIM is extending this idea to give more interactive access to notifications and dialog boxes. N4BB scored two slides showing off how RIM is implementing this on BlackBerry 10. The two different types of toasts and dialogs are Cinnamon Toast and French Toast.
Cinnamon Toast allows users to preview messages from the lock screen. It progressively discloses more information based on the angle you hold the device. So say the LED on your BlackBerry 10 device starts lighting up. You just pick up the phone and when you start tilting the device towards you it shows you the message. At 45 degrees you will see the full message preview of the header, subject and three rows of text.
French Toast on the other hand is to undo a delete operation. This slide describes a delete operation that does not require a confirmation but rather uses a “Toast” to offer an undelete option.
I know of a few other tweaks coming to the OS but hopefully we will get some more leaked slides describing them!
