Notification for tasks or case for groups

[IgorA100]

There is a situation when a group discussion of a problem or a case is necessary.
It would be very good if you think over an algorithm for notifying all users in the group.
For example, if the responsible person is not specified, then notify all members of the group (if the group is specified). Or in the task (case) set the checkbox "notify everyone from the group" or something else ...
Also take into account the notification about the creation of a task (case) and when changing it in the corresponding feed.

This one is more business specific problem that one may solve by using Workflow tool, BPM or formula.

Thanks, Yuriy, for your reply.
I will study the "Advanced Pack" extension in more detail.
Is the paid extension code open or encrypted?
