Simple todos. You can super-quickly drop items into lists and remove them when finished. I'm a big fan of simple, straightforward stuff. Plus, it's a Dropbox away from simple cloud syncing. Someone get Cultured Code on the line THIS MAY BE RELEVANT TO THEIR INTERESTS!

"A collection of Python utilities for Mac OS X system administration.

The PyMacAdmin project started as a collaboration between Chris Adams and Nigel Kersten to develop a replacement for the unsupported 'kicker' feature included in OS X prior to 10.5. That replacement eventually became crankd, which provides a way to execute Python code or a shell script in response to many system events: network changes, filesystem activity, application launching, etc.

We've also added utilities to create network locations, manage proxy settings or update AirPort passwords using our Keychain wrapper."
