For this plugin to work, you must have a memcache(d) object cache file that has a stats() method. Otherwise it won’t display the panel in the debug bar section.

Second caveat is that you have to know the key & group to find the object you’re looking for. Which I guess the name suggests: Cache Lookup.

Basically, I didn’t really find the plugin useful for my needs, but maybe someone else will.
