Here is the way how I have added custom field:

using observer (subscribed on the adminhtml_store_edit_form_prepare_form event via adminhtml/events.xml) and

added field https://screencast.com/t/bUow3hzc73Aq In the admin part new field has been added successfully, BUT I have trouble with multiple values sending (event if I select couple values, anyway magento SENDS ONLY ONE value - https://www.screencast.com/t/GOyaXm1m).

Please Help me on this I fighting on this issue more than 2 days already. Maybe anybody knows about any existing restriction for Store View edit form?
