Is there a way, either in Gmail, Boomerang or in another lab/extension to create a reminder in your GCal (Google Calendar) To Do List?
So, before sending the email, there would need to be a place to enter the reminder date/time/message and which task list it would be added to, would it be placed at the top or bottom of the list, and so on.
This would be more helpful rather than either returning the message, re-sending the message at a fixed (or random) time in the future, etc. This would require Gmail and GCal to communicate with each other, either by themselves or via Boomerang. Is this possible?
