found out intellij is working on a gui solution for pulling github push requests.. cool! https://youtrack.jetbrains.com/issue/IDEA-85079

Why is there no GitLab integration in IntelliJ?

that's a good question

Reminds me of a situation with the older Linksys Routers where only a single dyn dns provider is supported. When the integration (service) broke down there were no other supported providers which could be used, hence users of the router were "up a creek without a paddle" as it were.
