"Lingon is a graphical user interface for creating and editing launchd configuration files for Mac OS X Snow Leopard. You can use launchd on a Mac to launch scripts and applications whenever something special happens or at a specific time or periodically. You get all launchd configuration files in a list to the left so you can easily see all and choose which one to edit."

boom lets you access text snippets over your command line. I'm personally aiming for exactly two use cases, but I'm almost positive there are thirteen more. Here's a couple examples:

Your own del.icio.us-esque URL tracker. When I make clever animated gifs of my coworkers, I tend to lose the URL, which is a total bummer since I want to repeatedly repost these images well past their funny expiration date. boom lets me easily access the good stuff for years to come.
Commonly-used email replies. Everyone's got those stock replies in their pocket for a few common use cases. Rather than keep some files strewn about with the responses, boom gives me them on my ever-present command line.
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!
We store everything in one JSON file in your home directory: ~/.boom. The structure is simple, too. Each individual item is tossed on a list, and you can have multiple lists.

"Search in files. Quickly.
VisualAck is like grep (or ack), except faster and with UI. For Mac."

"Stay ensures that your windows are always where you want them to be, even as you connect and disconnect displays."
