This plugin allows you to give your WordPress dashboard a fresh new look. Your admin panel will look clean and will allow you to focus on what’s really important for you and your users. This colours scheme is set as default and the plugin also prevents users from changing it.

danixland-user-panel is a plugin that adds a new widget to be used on the Sidebar (or wherever you like). 
This widget is an enhanced version of the standard meta widget, it shows the current user’s Gravatar (can be disabled 
in the control panel), shows a link to your site’s Dashboard, to the current user’s options and detects if a user is 
logged in or not. 
If a user is not logged in, the widget checks if user registration is enabled and shows different links based on how 
the admin set up registration on the site. 
If registration is enabled, the widget shows a link to the registration page plus the usual “login” and “forgotten password” 
where if registration is disabled, it shows only the standard “login” link.
This plugin allows the admin to display a set of custom links which can be shown based on usernames, user ids or even user roles and capabilities.
Starting with version 1.2 this plugin uses some code from the sidebar-login by <a href="http://mikejolley.com" rel="nofollow ugc">Mike Jolley</a>, so a big thank you goes to him for releasing this nice piece of software.
