New comment notifications
You guys really need to add a feature for new comments that are being entered. It would help keep everyone that is in the shared list up-to-date with the task in real time. The person who assigned the task would be able to reply if needed to help the person who is completing the task. In a lot of cases there are tasks that require communication for the task to move forward. The notification for new comments would help resolve all these issues that arise. This would make wunderlist hands down the BEST task app for any platform.
