IOW, anyone using Sunbird will sooner or later have to migrate to Lightning (unless...), and this means having Lightning work on top of one's mailer. I did exactly this when Sunbird nightly and daily builds both temporarily stopped being made for several consecutive days recently, and the "Calendar tab" in Sm-Mail is almost identical to the Sunbird display; plus, the 3-pane MailNews window now receives an optional "Today Pane" on the right with the events of the day. Lightning preferences are a new "section" in the Suite's preferences window, etc.
All in all, a very successful integration, I'd say.
