There was a recent discussion on WordPress about the latest MP6 admin plugin. This is currently released as free open source code for your WordPress site, and it allows webmasters to use a newer updated backend stylesheet. It is still a case study and not recommended for large productions websites as there may still be a lot of bugs not touched upon.
However if there are other forward-thinking WP users then you will likely want to try this out. I just recently installed the MP6 plugin on my own website and I’d like to offer some thoughts on my own opinion. You can download the MP6 plugin right off the WordPress repository or simply search for it by name in your WordPress plugins panel.
