Is there any possible way (theoretically) to have a world where this was updated when group members read the message via email? I had an announcement where I wanted to get a handle on whether or not someone had read it, and only a handful of the recipients showed up in the count; while I know others read it via the email notification.
I know users don’t read and it’s probably safer to use something like the Discourse Policy plugin to get a positive confirmation, but it sure would be nice to have a more comprehensive count, if possible.
