Remove and restructure the ‘Howdy’ line. Props to Ozh for <a href="http://planetozh.com/blog/my-projects/no-howdy-a-plugin-for-wordpress/" rel="nofollow ugc">No Howdy</a>.
People have always seemed to complain about the ‘Howdy’ on the admin pages. I personally don’t care about the use of the word but think that the ‘Howdy area’ could be more functional and user friendly.

While the “Howdy” message is suitable for bloggers and casual users of WordPress, it does not fit the bill for many projects requiring WordPress to be used as a true CMS. This simple, lightweight and secure plugin allows you to change “Howdy” to whatever text you would like it to say.
