It's been a while since I've updated the Caching Manager, which is a module on the Sitecore Marketplace, so during a recent upgrade it was about that time. I'm using the design from Sitecore 8. It's backwards compatible through Sitecore 6 (SIM makes this possible) so there's no excuse for not getting it. Unless, you're on 5? Was caching on 5? I honestly don't remember or probably never knew.
The what now?
If you've never seen the Caching Manager, it's a single .aspx file that can be used to view your cache settings from a running Sitecore instance. Sitecore provides a default at: /sitecore/admin
