Hi!
I've been working on changing the way article message templates look (and also structuring them in a better way). By "article message templates" I mean templates like {{WIP}} or {{notability}}, which add a small banner to the article giving the reader/editor some information about the article's state.
Check out User:Ondo/templates, where I've laid out three different styles (with four examples). I personally prefer style 1, but let me know your opinions! I have also structured how each of the four colors should be used, feel free to suggest any changes. I will make the changes in a week (or if most active users answer this post, whatever comes first).
Thank you!
