– users should only be able to mention someone in their own department. Is it possible to configure who users can mention?

- is it possible to configure what groups/roles/departments of users can see in their feet? For example, what if we want announcements to be viewed by all employees, but feedback only to be viewed by the user for whom feedback is intended? What if we want holiday announcements from the HR department to be viewed by all employees, but messages generated by users only to be viewed by users who are tag?

In general, we need to understand whether the feed can be configured or not.
