In 3.4.0b1 we changed the task views. From multiple views (filters) to two views: Simple and detailed. With the To-Do functionality task lists can grow rapidly and filtering is a good way to manage tasks.
Create task filters to quickly filter task.
UX: Similar to 'Unread' filter in mail view, but not a drop down. Place the filters next to each other (enough space in the toolbar).
Move buttons in a 'more' overflow button if the screen gets to small.
- Upcoming tasks (7 day view)
- Completed tasks
- Overdue tasks
- Active tasks
