Visualizing a project time line is a feature that is offered by all project management applications, and I would suggest that you look to these sorts of applications for immediate relief. Probably not what you wanted to hear, but at least a solution is available. Omni will point you to OmniPlan (which I use and like), but there are other alternatives if you google around.

Likewise, if you can't live without context tagging, you should checkout Things . . . apologies in advance if I've got the apps name wrong.
