Use Nickname instead of Username

Hi, your plugin is working perfectly, although there is still a couple of things that might be changed, for example to use Nickname instead of Username when accessing the Chat. The Username is rarely publicly shown (it often is the Admin name) so it could be quite bothering to show the Username when joining the Chat (even if we can change it, but still). Do you think it could be possible to change the default setting:

Integrates with WordPress user accounts to use login name (or Nickname) as chat nickname

Thanks a lot! ??
