I think you'll need to call the `IRelayCommand.NotifyCanExecuteChanged()` for the `CanExecute` to observe the status changes. i.e. something like this. ``` private void ExecuteDisableCommand() { IsEnabled = false; MyCommand.NotifyCanExecuteChanged(); }...

Thanks for the quick response! Yes, `FormattableWith()` seems to be helpful when we need to inspect the parameters or need some custom formatting, but I don't see if we can...
