As a GTDer, I use a lot of contexts and if things are going well, some of them may be empty (i.e. have no tasks assigned to them at a given point in time). It would be great if, by configuration, Toodledo would NOT list contexts in the context view that are empty. I don't want to see a context listed if it has no tasks - this is not useful.
I suspect the same would apply to tags for some people, but this is not important to me.
