Often getting client approvals can be a task (pun intended). Clients can sit on the fence when an approval is pending for them. It would be great to have a setting to auto-approve a task with that requires the client to click "OK" to move the task forward. For example, if the task is not approved in X days, it will be auto-approved. This might require an additional option for revisions whereby if a client submits revisions the countdown to auto-approval would pause/stop.
