I realized that `LocalAppWindow.current.height` is...

I realized that LocalAppWindow.current.height is the Dp height of the window (as Int) INCLUDING the OS window title, right?

Is there a target OS independent way to decide the height of the window title? (or is it always 28.dp ?)

I wanna determin the max "usable" height of the window, which seems to be LocalAppWindow height MINUS OS window title ...

I wanna determin the max "usable" height of the window

Probably there three ways to retrieve that:

val window = LocalAppWindow.current.window
// insets will be available only after we show the window (or call appWindow.window.pack())
window.height - <http://window.insets.top|window.insets.top> - window.insets.bottom
// or 
window.contentPane.height
// or
Box(Modifier.fillMaxSize().onSizeChanged { }) {
   App()
}

Depends on how it will be used

You can use BoxWithConstraints to get the usable height within Composable. E.g.

Window(...) {
  BoxWithConstraints(modifier = Modifier.fillMaxSize()) {
    println("${constraints.maxWidth}x${constraints.maxHeight}")
  }
}
