How to create a recurring task in Google Tasks

Actually, marking a task as complete doesn't delete it, even after you choose "clear completed tasks". You can always view completed tasks. In the console view ( https://mail.google.com/tasks/a/yourdomain.com/canvas ) just choose the "Completed tasks" view. In Gmail or Gcal, you can choose "Actions/View Completed Tasks".

No, this isn't currently possible. (support posting) The quickest way I've found is to create a filter that applies a label to these emails. Then, I am able to open up the label, use keyboard shortcuts to navigate and open an email, and then shift+t will create a task for the opened email. Use a keyboard shortcut to get to the next email, rinse and repeat.

If a filter action to add to tasks is ever created, I'll just have to switch my filter action rather than creating a setup then.
