Yes, it is about the custom tables for manipulating kerning pairs in QuarkXpress that it seems many users would love to see in InDesign. It's an old and common feature request. Nothing i care for but of course I would call the solutions, that exist instead, less intuitive.
As I thought about it, I wondered if maybe there was a specific reason Adobe didn't want an implementation like that. Some people are guessing font licensing as an explanation, but does copying kerning values from a font count as piracy?
