Q: when I write a data class with multiple properties in the constructor, all of them are marked as used (not greaied-out) even when none are used in the code ("Find usages" returns empty). Removing the data modifier returns things to normal. Is this a bug or intended behavior? How can I quickly see unused data-class properties?

Arent they used in copy(), toString() and componentN() ?

[voddan]

Even if they are used in auto-generated functions, how do I know which properties are referenced in the code?

[spand]

I have no good answer to that last question short of making them all private. Just expanding on why they are not directly unused.

You can always press Alt + F7 on them to find the usages.
