I have recently updated my d12 Message Blocks plugin for WordPress. It adds two new message blocks: one with a title and no icon, and another with neither a title nor an icon.

Sometimes you need a message block that just has information in it.

Sometimes an Icon Detracts

If you need to highlight information without an icon, you can always have a message block with just a title.

You can get it from the WordPress plugin repository.

Development snapshots are available on my Git repo.
