BlackBerry really is working hard to bring back features users loved in BlackBerry legacy devices. The latest reveals from Michael Clewley on his BBM channel focuses on the BlackBerry calendar app. BlackBerry is finally allowing you to add tasks from your calendar in OS 10.3. They have also added a weekly agenda view. This lets you see more than just the current days agenda at a time which makes that view way more functional.
Last but not least BlackBerry is introducing a meeting mode where you notification profile will automatically change based on you being in a meeting. This is pretty awesome since I used to have to use a 3rd party app for this basic functionality.
