I don't know how familiar you are with Toodledo, but you can record any project-related items without cluttering the Next Action lists. That's just how I set it up. My Next Action lists (one for each context) do contain only those things that are actionable. I do this by means of saved searches. It is only when I have my Weekly Review that I look into the project lists with all items, both actionable and non-actionable.
