I agree. Context can be an available tool (phone), a location (airplane), a person (calling the boss now...), a mood (only rote work right now), a weekday (Sat chores), a goal (get some momentum going on fitness) etc.
This isn't about making things more complex as some have argued - it's about adapting to the way people work. Just because I'm online at Starbucks doesn't mean I want to only do the "online" tasks.
I think the key here is tagging which has been discussed elsewhere especially with regard to the pending alpha release of
Things by CulturedCode. My vote is to add tagging to OF and reduce some of the complexity and rigidity of the rules. At least provide some options in the prefs to override/modify some of the rules so I can tailor OF to the way I work. I really like OF but the more I use it the more I'm worried about whether I'll spend so much time worrying about the tool and whether I'm missing something that eventually I'll need to revert to something simpler.
But then again, OG apps usually kick butt and this is still an alpha right...
