Eyedropper to to show ink percentages in elements.
A tool that if you click on an element in the file will show you the percentage of spot or process color being used in that spot. Make it live so you can move around easily and not pick up the art. Similar to the info panel in photoshop. We use a program called PackZ that does this. A screenshot of the use of the eyedropper is attached.
If you open Color panel, pick standard Eyedropper tool, click and hold and move over the different elements, the panel shows you the color, in real-time.. but not the values of a spot color, just the name of it. So yeah, should be more than this, and a hint near a cursor is handy indeed. Voted.
