Eva, there is out of box no way to deactivate a record in the list_alg.htmpl file as there is no active/delete_flag attribute for the alg object. It is possible if customize the list_alg.htmpl file and detail_alg.htmpl file, after adding a custom zactive attribute. As for removing the whole tab(if I understand right), you can simply customize detail_in.htmpl and delete the tab. Thanks _Chi
