The new Default option for the email address used for outbound messages is helpful; however, it's highlighted another issue.
In the email/conversation view and HelpDesk, it's hard to see which email is active as the From address. This causes problems when customers reply to old tickets using our support@ address or accounts@ address about an unrelated issue.

Ideally, once you've set your default From address, you'll see a warning/note/highlight when your reply does not come from that default address/Default viewDetailed dropdown
