I’m in the bizarre position of actually using two different launcher programs on two different computers: my desktop has Quicksilver installed, while my MacBook relies on Butler. As the MacBook is my everyday machine, I end up using Butler more often, but Quicksilver catches my eye every once in a while.
For example, Tim Gaden from Hawk Wings tipped us on a new Quicksilver extension that lets you create iCal events from within Quicksilver itself. Such power demands complexity, and so the syntax of the event creation has a bit of a learning curve, though I think most people should be able to master it with some practice. The extension was created by Benjamin Hartley, who also created the ABG Merge app, which syncs your GMail contacts with OS X’s Address Book.
If you’re a Quicksilver user looking for a way to bring even more power to, as Tim calls it, the “undocumented mystery” of the program or you, like me, simply can’t be bothered to open iCal most days, perhaps this extension will be of use to you.
