I agree with commenter. My particular problems (not all about UI).
- Submenu is so gray its hardly visible (the one showing files, commits etc)
- Pipeline interface is horrible. If job is manual it cant be executed from the job page or repeated with latest code without resurfing trough menu.
- Project builds can not be deleted in bulk without using API
- Public projest are basically hidden, I have to explain to everybody how to find something.
- Snippets do not have comments if not part of project.
- Code review not possible outside of commit.
