Kahi's WP Lite for WordPress

There are always parts in the WP administration you don’t currently need. This plugin makes it easy to hide them – like unnecessary menu items or any of the boxes on the posting screen (like custom fields or trackback box). Unclutter the administration and work faster.

You can also input your own CSS code to modify the look of administration.

For more information, support, giving feedback, reporting problems (thank you for that!) or anything else – see the official plugin’s page.
