In `fuel\config\fuel.php` I have the following:
$config['settings']['footer_column_count'] = array(
'type' => 'number',
'min' => 0,
'max' => 4,
'label' => 'Number of columns in footer',
It works fine, is displayed in the settings view, and I can only go from 0 up to 4 when using the buttons on the number field, just like the documentation suggests.
However, anyone can enter the number '5', and it would persist into the database just fine.
I was wondering if there's an easy way to add custom validation rules to settings? For example use the `is_between` function in the `Validator Helper` class.
