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.

Better Howdy

Remove and restructure the 'Howdy' line by changing 'Howdy' to 'Logged in as'.

Greetings byGosh is a simple, free plugin that supplements the standard greeting “Howdy” in the WordPress admin dashboard. It displays a random greeting from around the world – the equivalent of “Hello” in 16 different languages. “Howdy” is also included in the rotation because I am fond of it, it just gets a little monotonous on its own.
Greetings byGosh has only been tested with the English language version of WordPress.
This update: (1) Tested with WordPress 5.6.1; (2) Added two new greetings in honor of Kamala Harris, the first female Vice President of the United States: ‘Wah Gwaan’ (Jamaican), and ‘Vanakkam’ (Tamil).
If you enjoy Greetings byGosh, please leave a review. If this plugin gives you any grief, please post on the support page. I’ll do my best to fix any problems.
