Reply To: What is the use script label panel?

Select any object and you can assign a label to this. At times very useful for use with a script, not that much otherwise.

I have the same reservations about the Data Merge panel. What's it for? Why doesn't it do anything when you open it? Can I safely delete it from InDesign, and if so, how? Et cetera.

Point is, InDesign has so many features, panels, and popup dialogs, there is a pretty good chance no-one uses all of them.
