One of the things I wanted to make easier was how to build a new action in OmniFocus based on an existing action. If I’m in Forecast, for example, and am completing an action, maybe I want to make a new action in that project quickly and easily.
I made a Next Action Shortcut for exactly this. It works by sharing an action in OmniFocus to it, then asks for a name for the new action, and then adds an action named that to the shared action’s project. For bonus marks, it adds a note to the new action showing what action it was created from, a link to that action, and that action’s note.
