Did you know there is a quick way to identify if a tool is a macro in your workflow? You can enable a plus sign to show right on the tool! You can also display an XML View tab in the Configuration pane. This is helpful to quickly see what version the workflow was saved as and to also see where any macros may be saved.
Example of the Macro Indicator
