Krumo as it's presented when page loads, collapsed and using very little space
Krumo is a debugging tool equivalent to print_r() and var_dump(), with the advantage of collapsing array and object values so that it takes less space and let us see only what we really need from complex data.
Hikari Krumo ports it to a WordPress plugin, so that Krumo becomes easily available in any WordPress page. Original Krumo has a few bugs fixed and has its options available in an admin page instead of requiring krumo.ini file edited directly.
