any better alternative to this?

var navEarliestChild = g.navWindow!!
            while (navEarliestChild.parentWindow != null && navEarliestChild.parentWindow!!.flags has Wf.ChildMenu)
                navEarliestChild = navEarliestChild.parentWindow!!

@elect use recursion

uhm, smells overkill

cool, I didnt know it, thanks!

Also I have hunch that

generateSequence

might help https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.sequences/generate-sequence.html
