This is a great plugin, so first of all, thank you! It has made debugging so much easier for me.
My one complaint is that it overwrites the WP_Dependencies entries for Koopersmith's Debug Bar Console plugin. On lines 147 and 148 of debug-bar-extender.php, you enqueue the style and script for the plugin with the handles 'debug-bar-console', thus re-registering those styles and scripts. I modified those lines to use 'debug-bar-extender' instead, and both plugins work perfectly now.
Whenever you release a new version, it would be great if you could include those changes.
