Passport - Parity with MJML, Upload MJML Issues
The ability to upload MJML to be used as a template in the passport editor is great, however I hope it can be improved.
Uploading MJML often results in errors -- provide more documentation for how to upload an MJML file to work with Passport
In Passport, it's great to be able to set global styles. However, it'd be nice to set styles for things like buttons, and other components normally available in MJML (including all of their related attributes).
Allow an email editor to see the underlying code in passport if they so choose.
