GitLab true dark mode

Description

A true dark mode for GitLab would be great! I know you can select some themes in the preferences but they only affect certain things like the sidebar. It is also possible to change the text editor style. I use GitLab rather like an application than a website. A option in the preferences to swap all the white panels for black and the text in a nice smooth light font would take some strain of my eyes. What do you think? Or am I overlooking something?

A workaround is using tools like StyleBot that change the CSS on the fly (https://chrome.google.com/webstore/detail/stylebot/oiaejidbmkiecgbjeifoejpgmdaleoha)
