Collaboration software for tracking questions/issues
I'm sure this comes up in places that are more dev focused, but it's lamentably uncommon in the circles I frequent. I'm looking for a way of tracking questions and concerns that come up over the course of a complex problem, and being able to associate those questions with the data and other questions (or future answers) on which they depend.
Anyone know of anything designed for this, or does it come down to keeping a separate file for documentation? Seems like that's a little crude.
