Log State transitions?

[Liam19]

Is there any way to automatically log state transitions including SubStates? I'm trying to debug my game's state and it would be great if there was a way to know exactly when the App State changes.

Edit:
Got this working with a few steps:

fn main() {
    App::new()
        .init_state::<GameState>()
        .add_sub_state::<GeneratingNewWorld>()
        .add_sub_state::<LoadingWorld>()
        .add_sub_state::<InGame>()
        .add_systems(
            First,
            (s_run_state_transitions, s_state_transition_logger).chain(),
        )
        //other app functions...
        .run();
}

/// Make sure state transitions are run before anything else for accurate timeline of "events" in stdout
fn s_run_state_transitions(world: &mut World) {
    let _ = world.try_run_schedule(StateTransition);
}

fn s_state_transition_logger(
    mut game_state_transition: EventReader<StateTransitionEvent<GameState>>,
    // SubState
    mut generating_new_game_transition: EventReader<StateTransitionEvent<GeneratingNewWorld>>,
    // SubState
    mut loading_world_transition: EventReader<StateTransitionEvent<LoadingWorld>>,
    // SubState
    mut in_game_transition: EventReader<StateTransitionEvent<InGame>>,
) {
    for event in game_state_transition.read() {
        if let Some(state) = event.entered {
            println!("ENTERED STATE: {}", state);
        }
    }
    for event in generating_new_game_transition.read() {
        if let Some(state) = event.entered {
            println!("ENTERED STATE: {}", state);
        }
    }
    for event in loading_world_transition.read() {
        if let Some(state) = event.entered {
            println!("ENTERED STATE: {}", state);
        }
    }
    for event in in_game_transition.read() {
        if let Some(state) = event.entered {
            println!("ENTERED STATE: {}", state);
        }
    }
}

I'm wondering if this is worth opening an issue? Seems a bit too involved for something as simple/common as printing state transitions.
