It would be helpful to users if the List Views in the My Actions View (and even the projects) had a separate category (similar to Team actions) for those actions assigned to multiple users. We often have users accidently closing out the action before all assignees have had a chance to complete their portion/track time. As a result, we have had to resort to creating a separate action for the same task for each individual assignee, which Hive certainly makes that simple enough to do by just creating one action with multiple assignees and click the little checkbox to have it auto create an action for each assignee. Managing all the extra actions for the same task from a scheduling perspective though can make it especially tedious and more likely to lead to errors, especially if you forget to create/delete extra cards for the task if/when you have people onboard/offboard the project.
