I would like to be able to have actions that belong to two lists/projects. For example, If I need to call my doctor . I would be able to tag it on the Health list, and Phone Calls list. That way I could have my items in their appropriate topic but I would be able to pull up all of the phone calls I need to make across all topics. Or write email tasks or shopping tasks. But items would still be associated w their topic and searchable by action required. I hope that makes sense!
