A very common use case seems to me that you want to know whether the build is currently “green” on the master branch or some other finite set of branches
This is on our 1.1 roadmap. I am told the design and front-end coding is complete, but it is waiting on some backend changes which will not be complete until after 1.0 is released.
I think we could build our own build dashboard using the drone API. But it seems like the idea of a red/green dashboard is a very common feature in CI systems and some variant of that would be great in Drone.
This came up a few years back  but the reason we do not have an official dashboard is because it is one of those things that people are very opinionated about, and I feared it would become a source of unbounded requests for changes, tweaks and customization. For this reason we have encouraged the community to create and share dashboards on GitHub, and then fork and modify them to meet their specific needs.
With that being said, if a company offered to hire / contract the Drone team to create a dashboard we may reconsider our position.
