It would be nice with a small pop-up/notification in the system tray of windows / mac / linux when a workspace completes. With the following information for instance:
"Workspace myworkspace.fmw Completed Successfully - 1 hour 32 min - 8 files written - go to outputcatalogue here: link or open workspace here: link"
Then you can easily go to the outputcatalogue and you can easily navigate to that workspace.
