This is the final piece missing for me to convert to icloud.com email. The lack of message grouping within icloud.com emails makes the UI extremely "busy" by showing a lot more messages than it needs to. Anyone who has had a back-and-forth email conversation viewed in icloud.com knows what I am talking about.
The email UI could use a lot of updating, but I'm personally willing to sacrifice some much needed updates for a message threading by conversation (which is the standard of every other online email service on the face of the earth)
