The field settings is ignored

Hello @petr illek, and thank you for the report.
Yes you are right this module not working with Drupal 10 because the module using hook_field_widget_multivalue_form_alter which has been replaced by hook_field_widget_complete_form_alter see https://www.drupal.org/node/3180429 →
I'm working on it to adapt the module code to new hook.

Since we gonna change the implementation it's better to work on #3167013: Use widget setting instead of storage setting? →
I guess it's time @mandclu

@petr illek can you please test release 2.0.0-alpha4 !
