This plugin allows you to add a sliding login/dashboard panel to any WordPress Theme. This awesome panel is based on http://web-kreation.com/index.php/tutorials/nice-clean-sliding-login-panel-built-with-jquery/
Instead of modifying directly theme files, just install this plugin so you can preserve you panel when switching between themes (or after themes updates).
You can also specify your own HTML content to put in the panel… Yes! this is awesome!
