make negative Filtering possible? #81

What would it take to make it possible to use negative or subtractive filtering? e.g. "-@home" would show all tasks except those with the context of @home.

Also, along the same lines, what would it take to make OR filtering possible? e.g. "@home OR @errand" would return tasks that have either of those contexts, not only tasks that have both (the current behavior).

Some level of this already exists: https://github.com/MartinSGill/TodoTxtJs/wiki/Filters

I have thought about this in the past, but mostly I found that with a project and context assigned it's very easy to find things. That's why I've only implemented the "no project" and "no context" filters.

Is there a specific scenario where you feel having these extra filters would be really valuable?

Hi, negative filtering is useful to clean future tasks, that need another task be finished or you have in a backlog, waiting to something. You can tag these tasks with +pending or +waitingFor. Note that the opensource Android app simpletask supports this feature.
