I have an idea for a feature. I have several workflows that I have to split up because there is a task that has to be performed manually, I would like a feature that sent a mail to a defined mail account (or group of addresses) and then waited for a konfirmation before continuing with the next task. The length of time it waited should be a parameter defined time inteval as should the action on timeout ( either continuing or stopping with an error state). I suggest that the mail should include a link that has a guid in it so that clicking on the link confirms that the job can continue with the next task. I know this means providing a web interface!
