Not having a hierarchical view of tasks belonging to parent tasks is really getting in the way. And I think everyone expects a hierarchical task organization, so ditching multiple parents would be a much better compromise for us to get what we need here. In the absence of that, I'm going to try to get us to something taht works better. I'm relatively new to Dropbox and have used lots of other task management tools in the past that work much better in this way. So I am going to try to move everyone to something else. I wish that Maniphest did this for us.
