In the Configuration Checklist at http://mysite/civicrm/admin/configtask&reset=1
, clicking on From Email Addresses takes you to the top From Email Address that you have configured, not the list of From Email Addresses.
This is a bit weird, especially if you have more than one From Email Address, which I'm guessing a lot of installations would have.
To get to the From Email Addresses list you have to use the Navigation Menu. It's the same on the demo site.
Is this a known issue or intentional? I hesitate to file a bug if that's intended behaviour.
