For debug purpose TestStand and other programming languages provide a "Watch Expression" feature. Similar to this I would like NI to add "Watch Variable" feature in "View" menu:
When user would click on "Watch Variables" a he should be able to see all the locals and globals used in entire VI hierarchy and select the variable that he wants to Watch. These variable should be displayed in another floating GUI. This feature would be of immense help even when we want to debug an executable where probes can't be used.
