Docktopus lets you to place informational badges on your Mac OS X Dock icons (similar to how Apple's Mail displays unread messages). With these badges Docktopus gives you instant access to useful information and powerful commands right from your Dock icons.
Application CPU and Memory usage, a folder's contents, available disk space. These are just some of the information you can display using Docktopus badges. Keep an eye what your Mac is up to with just a glance at your Dock. These badges update in real time so you are always in the know.
Yes, the Dock is useful for opening apps and documents, but the Launcher badge takes it to another level. This badge acts as a pop-up menu and can run (not just open) QuicKeys Shortcuts, AppleScripts, Automator Workflows, recently opened files, or even specific collections of files and folders that you specify. Whew! Yeah, Docktopus makes the Dock pretty powerful!
