[SOLVED] - Show or Hide Debug Bar

There is also the possibility of removing it (whilst still in the development environment, and on-the-fly in one's active code, if that floats your boat) using settings in \Config\Filters.php:

Code:

public $globals = [
    'before' => [
      ...
    ],
    'after'  => [
      ...
    'toolbar', // <= comment this or remove it from $globals to disable the debug toolbar
    ]
