Perhaps this is something already out there but I would like to create a task automatically when another task is completed. For example, I have a task for a client and when I complete it, I would like a “bill client” task to be created, possibly from a template.
You should be able to run a OmniAutomation Plug-In with that task selected and create a new task. Event-triggering is not yet implemented, as far as I know. You must run the plug-in manually.
