Load more information in notifications

[laughedelic]

I got a bit confused by the setting "Load notification details", I thought it also loads the content of the notification, but I see now that it's only about status, etc.
I'd really like to turn off mail notifications, but you can see that they provide much more information right in the notification body:

I understand that with the v3 REST API you need to do another request to get the comment body, but if it was under an option, I would definitely turn it on.

This may be a bit tricky because GitHub fires notifications for distinct events. So question is what to load/show exactly for distinct event types.
