• Disconnect terminal connections
  Left click the connection, then, press the Delete button.

• Show terminal names
  FlowDesigner for Windows does not always show the terminal names. You can see them by putting the mouse cursor on the terminal. During the connection, you can see the terminal name and its type when you put the mouse on the terminal.

• Not implemented functions
  FlowDesginer for Windows does not support the function to turn the arrow color to red if the source and destination terminal types are different.

  FlowDesginer for Windows also does not support the function to reorganize the connections.
