A smaller maintenance release of my Admin Quicksearch (WordPress Plugin) has just been committed.
The 0.2 release improves the display of the quick-search-text-box and the formal quality of the source-code.
Admin Quicksearch speeds up a site owners tasks on the dashboard as it allows to search and reduce the menu of the dashboard and some plugin lists.
I play with the idea to provide quicksearch on the widgets screen as well as it gets more and more crowded.
