It would be useful to have a place to view/edit all profiles that a library has created for use while staging MARC records for import in one place - maybe similar to 'Manage MARC modification templates'. It could include each profile's settings and the ability to delete individual/multiple at a time, and if possible, the ability to add new, edit existing, and/or duplicate to create new. But at a minimum, being able to see what exists and delete from there rather than the 'Stage MARC records for import' screen would be helpful.
New Koha library cosigning this bug -- we'd love to have a more obvious and intuitive way to view, edit, and delete these profiles.
