@happyDemon I'll have a look the next coming days

Took a look here and I don't see anywhere in the nova code or in the nova-grid-system that adds a field.class property. Where specifically is that coming from? I don't disagree the addtl div is probably not required, but adding something that's field specific feels very specific to someone's specific usage.
Also if you do want to move forward, if you can remove the dist js you updated here. We will build prior to the next release.

@happyDemon, this can get merged if you remove the compiled JS file (field.js) from the PR. Would love to have this right now.
