Does `LaunchedEffect` have any meaning on Desktop? Since there's no android lifecycle here?

Of course. It launches a coroutine once the current recomposition completes

I used to be a reasonably competent developer. Moving into management has dulled those senses. Or maybe I just don't understand Compose.

Compose has its own lifecycle stuff. Not quite the same as the Activity lifecycle but more related to entering/exiting the composition tree. But still lifecycle somehow.
Actually back to Activities lifecycle it has its similars in other platforms too. UiViewController didViewApper and willViewAppear in iOS, minimize/restore desktop and Web

```    LaunchedEffect(state){
        println("State changed: $state")
        window.title = "Corbel Editor: ${state.value.mode.name}"
    }```
I thought this would be 'fired' every time `state` changes (where `val state = viewModel.appState.collectAsState()`. Though to be honest I don't know what needs to change for this to count as a.... change? Because calling `state.appState.mode=Mode.BUSY` definitely doesn't count.

Use `by` instead of `=` or, collectAsState(). value
You are keying LaunchEffect with an instance var that doesn't seem to change. If they doesn't change the effect won't retriger
