Custom Element libraries for Messages
As a developer, I want to create a library of reusable components and any user could build their own messages using these reusable elements.
Ultimately this user should be able to drag-drop these elements into the message. Then up date the copy, links, and images with out having to look at or touch html.
This is *sort of* achievable through content tags, but ultimately not friendly for folks who aren't familiar with html, or email html specifically
