Creating Dynamic or Shared Content modules that work with new responsive editor has proven to be a bit tedious. What we need to do now is send a test email, open the email in a browser use a developer tool to copy the module code and past that to the dynamic content editor.
This could be made a bit easier with three alternative methods:
1. Incorporate the email editor tools to the dynamic and shared content editor
2. Add a "Export layout module to..." function to the email editor. This could be used to export the layout module to Shared Content or Dynamic Content.
3. Allow layout module HTML to be copied from the email editor and pasted to Dynamic or Shared Content.
The first one would require more work from development and the last one should be quite fast to implement.
