Approvals are a bit limited. An approver cannot log into port and see his own approvals. Only Admins can see outstanding approval requests.

The information to the approver is very limited- when they see the approval link, they need to view the json payload to see the details of what they are approving.

Suggestion is that Approvals move to a blueprint model whereby all of the existing goodness, customisations and automations can be inherited to this workflow for free.
