In Wordpress 2.5+, a new administration menu was introduced for Wordpress which takes a lot of useless space and also splatters a lot of links over the screen. Plus the other downside is having no drop down menu so you have to manually navigate to each page.
Planetozh has coded a very neat and useful Wordpress plugin which will not only kill all wasted space in Wordpress administration menu but will also add a css drop down menu for fast and easy navigation.
The basic feature of this plugin is to get rid of all unused space in Wordpress admin menu and instead insert a new menu on the top dark grey bar which makes the layout more compact and easy to navigate.
To install the plugin on your Wordpress blog, simply upload it to your plugins folder and activate it. It is even compatible with Fluency Admin Theme for Wordpress.

I have been using Lighter Admin DropDown plugin for a long time, it also does the same.
but can’t say it is compatible with latest wordpress
This one is good.. cleaned up all unwanted entries from Administation panel.
Been using Ozh’s plugin for two or three versions of WP
It is so useful that it is one of the first plugins I install.
This is new for me, will definitely give a try to this.
