Post View Count used the WordPress.com stats API to add a sortable column to the admin’s post manager, displaying the view count for the last 30 days for each post. This plugin requires the Jetpack plugin to function.

Author Wordcount is a simple tool that allows you to enter the title of 
a work-in-progress (I’m looking at you, NaNoWriMo draft), a current word 
count, and a goal word count. These counters can be updated when you have 
new words available, and can be deleted when you’re finished. You can have 
any number of works in progress at a time, since if you’re like me, you’ve 
probably got a huge collection of drafts just waiting to be finished.
The style is based on an old component that used to sit on the sidebar of 
<a href="http://hughhowey.com" rel="nofollow ugc">Hugh Howey’s website</a>. Thanks, Hugh!
