I also like the idea of tags for both contexts and projects. There could be a setting to limit to one tag per item (equivalent to the current system) or many tags per item.

Omnifocus is a great program. The many tags option would allow me to place the same blocking item or general action into multiple projects to allow advancement when the one physical action is complete.

Allowing tags for multiple projects would also allow me to setup a daily project, a weekly project and a monthly project where I could designate actions (or perhaps even projects) that I have as a goal for completing each day, week, or month.
