A very nice touch we discovered in the Model Tab is that hovering the mouse over the name of an operation brought up a 'tool tip' display for the signature of the operation. Also new in TJ3 is the ability to manage the display of multiple diagrams through the use of tabs in the Diagram Pane. This allows you to quickly find the diagram you want to view when multiple diagrams are open. Hot keys for zooming are very effective. Overall navigation scheme is logical and well thought-out.
Tabs allow multiple diagrams to be accessed easily.
