The only thing, which doesn't really depend on you I assume :), is I wish GitLab was used more often as an authentication mechanism by other services. I don't know if GitLab is actually an OpenID provider or if it's just because it's not popular enough yet.

GitLab can be an OAuth provider since version 7.7 [0]. I think it takes a while for this to be adopted by other services.

Any advice or help improving this situation is welcome.
