Assigned tasks from shared boards should show up in Next 7 days and All my tasks. Doesn't make sense to have assigned tasks NOT show up under a view called "All my tasks"! All means all ;) Additionally, the more flexible approach would be having a filter for assigned tasks across each shared board with the ability to toggle on/off all boards or select and choose which boards to show/hide assigned tasks from. Default could be show assigned tasks from all boards and possibly save previous selection and maintain state. I realize that My day view attempts to show what is contextually pertinent but there is currently no ability to view all assigned tasks across all shared boards in one place so this would app that function for both Next 7 days and All my tasks.
