why can't an interface inherit from a class ?
the use case would be using properties of that class in the interface's default function implementations

Because an interface has no storage, you can't instantiate it. A class has storage, it can be instantiated.

If an interface were to inherit from a class, it would have storage and be a class (not an interface).

The interface can inherit from another interface that already has default method implementations.

then is the only way to achieve what i want to create another interface that "mirrors" the class ?

<https://kotlinlang.org/docs/reference/classes.html#abstract-classes>

but if that class already inherits from another class ?

Take a look at interface *delegation* and see if that helps you do what you want to do.

oh yeah i've heard about that. will take a look, ty
