The screen refresh setting is no longer an option in the new version of the software. The setting is still there, but the option has been disabled. This is something we have reported and it's unclear at this time whether that functionality will be restored.
The embedded screenshot you were referring to had to be approved by the moderation team and should now show up when viewing that post.
As for the kudos box colors, that would require a UI enhancement by the Verizon management team. They are looking at the feedback left in this thread and will probably respond to that from their perspective.
