Hello devs, Recently in a MR discussion the topic came up of contributors being frustrated about lack of reviews. As a contributor and as a reviewer the lack of tools to find MR's in need of attention also frustrated me often. I suggest two new MR labels: Label: "review-needed":  If a contributor has an MR which he considers to be blocked on (lack of) review he can assign the label to clearly signal this. Label: "changes-required": This is the inverse - if a reviewer looked at a patch and it's clear that the patch needs more work from the contributor this label can signal this. What are the benefits? * As a reviewer I can look for MR's tagged with review-needed and can be sure that time spent reviewing is not wasted. * As a contributor I can mark a patch as changes-required if I think my patch is ready to land, or if I need input on the design. * Core maintainers can more easily identify patches which have been stalled for a long time, making their review a priority. The obvious downside is more labels. Cheers Andreas
