One of my favorite productivity Mac apps, Alfred, released its biggest update since it was first launched to the public over a year ago. One of the major features you will find is the ability to create Workflows, which are sort of like Automator scripts where you can utilize keywords, hotkeys, and other actions to perform tasks like accessing your local weather forecast, toggling Wi-Fi on/off, and connecting to your favorites on Transmit. You can find loads of workflows created by users on the Alfred forum.
Workflows is a huge game changer for Alfred. Version 1 already allowed you endless ways to customize and mod Alfred to your liking. It reminds me of how Sublime Text 2 became so popular when developers started building useful plugins to extend the capabilities of the text editor. Some prescient user has even taken the initiative to create a Package Control-like workflow that allows you to update and install workflows you install that were created by various authors.
