We run a microservice architecture w/ 100s of GitHub repos. Just visualizing the status of all of our builds is difficult; we use Insights, but it's a) Slow, b) has a bunch of information I don't need, and c) very clunky to navigate. You can't easily see what broke a particular build or who, or restart/rerun a build (or multiple builds).
This makes this otherwise great product hard to use on a daily basis.
I recorded a video describing some of the challenges and demonstrating how it's unwieldy - I don't want to publicly show it but would love to share it w/ any product manager who wanted to see it.
