Sure, you can set a shortcut to admin/config or install the devel module, but what if you could clear your cache with one button?
This small module adds a flush cache button to your menu for easy, one-click cache flusing!
It could add years back to your life, and your wrist.
It has no configuration, just install and enable.
You may not want to use this on a production site - or at least disable it when you go live, since a permissions check might not be enough to prevent an unauthorized user from flushing your cache.
