This has been requested many times before, and it is apparently in your pipeline. But it's been there for so long, so I'm worried you may have given up on it: Do you still intend to implement "Area of responsibility"? When at work I want to be able to make all private tasks invisible, and vice versa. It would be really useful (and I have tried to jump ship and start using Get it Done or Nirvana several times because of it, but I keep coming back to doit.im).

If you are not going to do it, how about making it possible to not only select a tag in the different Focus views, but also to exclude a tag. I could exclude all tasks tagged as "private". (Simpler than tagging all my work related tasks with a "work" tag, because there are so many of them, and they are tagged with so many additional tags.) Alternatively, make it possible to select more than one tag - I could select all that applied to work/private.

And if you cannot do that, how about making it possible to make "is not" searches. (E.g. Tag is not "private".)

Please?
