When using LDAP, CAS or even Koha, sometimes the existing texts shown on the opac-user.pl page don't fit when the login failed or when you are asked to login after trying to access a feature (try to place a hold without being logged in first) Right now it's really hard to change something here with OpacUserJs or CSS, because the text is in multiple <p> tags without any classes or ids. It would be nice if it was easier to select the elements.
