Hello - 

Our company uses email-to-case within the Sales Cloud.  We are currently going through our Lightning readiness report and trying to identify all of the benefits of using email-to-case and cases in Lightning.

We are currently using a Visualforce page that shows all emails related to a case.  What our users like is that the subject line of those emails are Bold, indicating that the email has not been read.  I didn't see a Lightning component that does the same thing.  

If anyone is using email-to case in Lightning, how are you letting users know that emails have are read or unread?
