Feature Request: task living on multiple lists (or customizable smart lists)

[Art_JB]

The "My Day" list is a great concept, but I'd like to see a more general version. The way I currently work is I maintain multiple to-do lists for different areas of activities. And I'll add items from the different lists to "My Day". But I'd also like to be able to plan out "My Week", WITHOUT the items getting moved from their original home (just the way "My Day" works) It's fine if it doesn't "auto erase" the way My Day does.

@Art_JBI want to underline that this would be a wanted feature!!

I agree, a customizable smart list or filter options on lists is defiantly needed.
a way to show all my tasks, flagged emails and tasks assigned to me in one list.
