A quiet pointer to the Pro add-on: an Upgrade to Pro link on the Plugins screen, a one-line note at the foot of the plugin's screens, and a single dismissible notice once the plugin has done its job. Nothing in the free plugin is locked or changed, and all three disappear when Pro is active. - New `dragonsmtp_test_email_sent` action fires when a test email goes out.
