columns_settings.inc is used from many templates, but sometimes it's not needed. KohaTable - columns_settings.inc kohaTable (DT REST API wrapper) - datatables.js If we do not use KohaTable we should not include columns_settings.inc
% grep -l 'columns_settings.inc' **/*.tt **/*.inc | xargs grep -L 'KohaTable' This could provide a first list, but it's not accurate. For instance: koha-tmpl/intranet-tmpl/prog/en/modules/tools/batchMod-del.tt is a false positive (we use KohaTable from another js file)
columns_settings.inc is going to be removed on bug 26553. *** This bug has been marked as a duplicate of bug 26553 ***
