I like the numbers that now appear to the right of the Next Actions, Today, and Focus list names, but they always show the total number of actions, even if an Area Filter is being used.
I suggest that you make these numbers reflect the current Area Filter selections. For example, lets say I have 20 total Next Actions, 12 in my "Work" Area, and 8 in my "Personal" Area. If I don't have any Area filters active, I would expect to see 20, as I do now. However, if I have my "Personal" Filter turned on, I would expect to see 8 beside Next Actions, not 20.
