Adding or deleting GitHub project labels on issues

Since projects got added to GitHub, I started using it more and more. For Front Matter, I am using projects to manage its releases. Before projects, I used milestones, but with projects, it is easier to follow up on what things I still need to do before the release. GitHub Project example from Front Matter One thing I was missing was a sort of label in the issue list to easily spot which issues were already added to a project release.
