With 4 years of feedback, I hesitate to think any comment here will actually be seen or taken into consideration. Every tasking tool I’ve ever used has the ability to share tasks which is necessary for collaboration for any company beyond one individual. It’s great that you can reassign a task, but we do this many times per day and the person who reassigns the task loses sight of that task once it’s reassigned so the only way we’ve found to not lose sight of it is to create a second, redundant, task to remind yourself when you’re waiting on confirmation that the reassigned task has been completed. I hope this illustrates the necessity for multiple assignees with a primary person responsible.
