Activity feed / Rights system for Planner
The ability to limit access to planner tasks e.g. only the creator of a task can delete it. Right now anyone in the team just could (accidently) delete a task without anyone know about it. Also, a "activity feed" in the main Chat would be nice, so users know when someone comments on their tasks or creating a new task with you as the responsible person. Right now you have to look at the planner what your tasks are without any notification.
