Project-wide tags (easy Areas)
Allow the creation of tags/labels on the project, that get inherited by each task in that project.
This allows maintaining very simple area tags, and organizing entire groups of projects all at once.
Example tags would be:
This would allow creating the @work area, and the @personal area, enabling a new layer of focus. E.g. see only my work related tags. This is possible, but one has to tag __ALL__ tasks in every single entry (e.g. @work for every work task, no matter what the project is).
