After working on the 8.x upgrade I have two major requests with regards to the Emails module:
1) When replying from a Case, the settings need to allow emails to go out From group email accounts - without identifying the particular sugar user. There needs to be an easy way to set the outbound From to the original email's inbound-email address.
2) the To/Cc/Bcc lines need to display the email addresses. Currently they only display the first and last name, they need to show both or have an option to choose which to display. Users are used to seeing the email address in the To of any email client they use.
