One of the most important features in Myriad is full AppleScript support.
AppleScript is an incredibly powerful and easy-to-learn scripting language in OS X. It's an indispensable tool for complex workflows, automating repetitive tasks and interacting with other applications.
AppleScript is so powerful we've made it a fundamental part of the way Myriad itself is built. You can access major functions in Myriad via external scripts.
