in version 7.0, as one example, the purchase order double validation works as expected when PO amount exceed the specified amount limit, system triggers PO waiting approval status, actually system generated PO approval workflow instance with basic information such as workflow ID, User id, resource type(model),resource ID, but only after goes to the Purchase order list the PO approver gets to know there are POs waiting approval.

I am wondering whether it is possible

1. extend the workflow instance to include more useful information, such as priority, workflow date, approver, action date, comments
2. make workflow instance list as part of inbox which integrated with messaging system, from this list, the managers can easily have a glance on documents waiting approval, also easily navigate to the document for approval with remarks when needed.
