- Make it easy to choose all open or closed tasks.
- Make "special" tokenizers composable.
- Get viewer() generating documentation properly.
Also, how useful do you guys think min() and max() functions would be for priority? I'm inclined to wait for users to request them since they seem less clearly useful than open() and closed(), but if you'd definitely use them I can build them now.
For example, you could use min(normal) to select all tasks with priority normal or higher.
