Hi @daileytj and @JeffGreiner-eaton please review.

[JeffGreiner-eaton]

screens in both themes look good with enabled & disabled buttons...Just see comment above.
Also I didn't dig in to why the message content has like a onFocus set so it looks like its clickable

• notice the divider changing weight here or my eyes playing tricks on me...

• changing weight here or my eyes playing tricks on me.

How can I reproduce this? Did you disable both buttons?

You have some merge conflicts now so be sure to resolve those. Could you update your demo to match the pattern I've set up for the CreateNewOrgBaseScreen? This away it'll be easy to demo and test. This also keeps the repo and example clean since we can rip out all of the demos from one place at the end.

@daileytj Added a new URL for demo. Please review.
