more flexible smart filters / groups
Idea is to create smart groups like "Area = Any Area" AND "Focus = Next" AND "Tag = Errands" .... or another example "Tag = @Computer AND (Area = "Work" OR Area = "Personal"). Take a look at how UltimateToDo app on android constructs "My Views" : very useful!!!
I really miss this feature from Remember The Milk.
I would especially like it if they added a "NOT" field, so you could select tags to exclude from the smart group.
