David Cramer and Rob Hudson have published a great debugging toolbar that has plug-in 'panels' to give quick access to useful debug tools such as a SQL query list, profiler, cache stats, HTTP POST & GET variables, and more.

I've always included a "debug.html" in my page footer but it only shows me SQL queries and execution time. I think django-debug-toolbar will now quickly become part of the standard toolkit of many serious Django developers, myself included.

Thanks to David & Rob for sharing!
