I've got a number of development plugins installed and this brings something new to the table. Love the ability to see all the hooks, classes, functions etc and to quickly see where they're being used and triggered.
A really handy plugin for finding out active plugins, WP version, active theme and many other options that are clearly tabbed out from the plugins main tab.
