In the old WCA experience, our marketers could share direct URLs to edit mailer templates in the author - ie https://engage3.silverpop.com/ux/#/composer/36183828. This made it much quicker for marketers to specify which mailer template they were working on (and if they required assistance) share it with the rest of the team - to prevent confusion.

After the update, there is no more direct URL - it's all masked under https://www.customer-engagement.ibm.com/campaign-automation/Email/Manage/Mailings_and_templates. This is very annoying because there is no way for marketers to easily share their mailer template in Composer unless they take note of the Mailing ID which is not accessible when in Composer - only on the Dashboard.
