Please improve your mobile UI - phones have lesser horizontal space than vertical. You have put a cool looking sidebar on the left side which takes up a lot of space causing text layout to be funny on my 5.2 inch LG G2.
You should be able to collapse the left sidebar. But we are the mobile UI has deteriorated in the last few releases and we plan to look into it in the coming months. If you want to get paid to contribute, we're hiring front-end engineers https://about.gitlab.com/jobs/
Github OTOH has an extremely usable mobile UI.
