Jane Wells, of Automattic, made a post on the Make WordPress UI blog, about some upcoming changes to WordPress.com. These changes aren’t necessarily going to make it into the WordPress Core, but it’s a possibility.
Jane had more to say about the changes,
The secondary button (Add Tags) looks a little too much like a Windows desktop toolbar item for me b/c it blends into the background so much, but that primary button (Publish Post) grabbed me right away. In 2.7 we introduced colors in the Dashboard Right Now box — green, orange/yellow, and red — to indicate different statuses.* We always meant to integrate those colors into the rest of the wp-admin design, but never really got around to it beyond coloring delete links red and pending links yellow. ‘Green means go’ is a pretty universal metaphor, thanks to traffic lights around the world. This button is a little too subtle to stand out as the primary action on an action-packed screen like post-new.php, but maybe with bold text and an outline (or maybe an actual green button, or maybe something else) we could consider a shift to using green in the primary buttons.
These changes could very well make their way into the WordPress Core, but it’s not set in stone yet.
I’m certainly a strong believer that the WordPress Admin interface needs continual development as it still doesn’t feel perfect — nor do I think it will ever be perfect.
Plenty of growth to take place, but I feel this would be a great step forward.
