acf-quick-edit-fields looks to be everything I need … apart from an issue where I can’t add values to existing custom fields (field is a Checkbox – not sure if this is relevant). It seems to overwrite existing field values every time. Is there a way round this? I can’t see any magical options to so.
Alternatively the Custom Field Bulk Editor plugin also appears to do pretty much everything I want, and does have a “Add value” option … but that specific option doesn’t seem to work for me. Arrgh.
