Speaking of UX, would you consider improving the look of Markdown rendered text (usually README.md) in the repo browser? On GitHub they look great and it's a pleasure reading Markdown formatted text there. In GitLab it's however not very appealing. Headers, spacing between them and paragraphs doesn't look very good IMO.
Coming from a previous job where we used GitHub and TeamCity, something I miss with GitLab is the ability to create a pipeline that's not connected to a specific Git branch. I'd like to be able to create a pipeline that can be triggered manually, without first having to create a dummy branch to put a .gitlab-ci.yml there. Is that something that's on your roadmap?
