'Offline' notifications for followed topics

[rgf100]

In 3.4.x, we have four options for notifications

Immediate - you get an email for every reply

Offline - you get an email for the first reply, but then no more until you log in again

Daily digest

Weekly digest

 

4.0 seems to have removed the second, offline option. I struggle to see why, as for heavy users it provides a necessary halfway option between 'fill up my inbox' and 'hide everything in one long email'. 

I might not want to wait 24 hours to know a topic's been updated. But similarly, I don't want 20 emails about it. 

Am I missing something here?

I'll give this one, forlorn, bump....
