This includes showing message details, which feature an action bar to react on a message. In the case of the 4-eye workflow, we'll have an "accept change" and "reject change" action there.

For the integration in Pulse:

• create a new "work item" message type
  • show the work item message in the list of messages in Pulse
  • fix the filters in Pulse: "work items" should only show items of your work item message types; "problems" should show warnings and errors; "info" should only show info messages
  • use the blue info message banner to signal the user, if a new work item has arrived

• open the message details in Pulse, if a user clicks on a info message banner or the message in the messages list

• if a work item action in the message details has been executed
  • close the message details pane and show the messages list again
  • if the action was executed successfully, show a success confirmation indication on the messages list
  • if the work item was canceled or deleted, show a cancel confirmation indication on the messages list
  • we might want to ask the user, if he really wants to cancel/delete a work item, before actually doing so. I could live without that, however.
