You probably already know that you can quickly view a summary of the input data for any object in your model with the Inspection Window. Simply place the cursor over a pipe or junction and 'right click' your mouse ('left click' for you lefties).

Think how handy it would be if you could also see a summary of output information on the Workspace. You can and it's as easily done as viewing the Inspection Window by holding the 'ctl' key down as you right click.

P.S. - In case you didn't already know, holding the 'shift' key down while right clicking will display an object's status, including what information is still needed to define an object.
