How do you use the VI Hierarchy Tree?

[Xenon]

I wonder how people use the Hierarchy Tree?

I would like to able to control the order of the VIs in the tree (all the VIs associated with XXX first, the ones associated with YYY second, etc.) But I can't seem to do that. I can move a VI up and down and group them, but then if you do anything (redraw, open/close, etc) you lose that reorganization.

So, I wondering what other people use the Hierarchy for? What information does it give you?

The VI Hierarchy is a quick and easy way to show how VI's relate to each other (i.e. this VI calls this VI, etc). The hierarchy can also show where the VIs are saved (by checking View >> "Full VI path in Label" and placing the mouse cursor over the icon). There are also many options available to the user by right mouse clicking on the icons themselves.

Unfortunately, you cannot modify your application just by moving the VI's around in the VI Hierarchy utility.

In addition to Archimedes' response, I just want to say that probably the best usage for it is when you are looking at an application developed by somebody else. It helps by giving you a big picture of that application, without digging inside.
