Community notification emails: Previews and turn off notifications for the thread

When getting email notifications from subscribed community pages it would be great if there was a preview of the message in the email - this was you can easily scan and delete without having to log into the community. Sometimes we get bombarded with emails based on other users responding which can be distracting when trying to work.

Also it would be great if you can turn off email notifications for a specific thread.

I think the above options would reduce the amount of unnecessary emails that I end up just deleting as there are far too many.
