Blue Ocean dashboard shows a list of projects + favourites. To access a build that was just triggered automatically (i.e. by a push hook), a user has to search for the project (if it was not added into favourites), click on the job to drill down, then click on the build to actually get into the build itself and monitor its execution. For organizations that embrace microservices or reusable code approaches, that would be a typical flow, as adding all the dozens of projects into favourites makes little sense.
In Classic UI, the build queue (both active and pending builds) is displayed on the initial dashboard and user can get into the build with a single click. Moreover, the build queue is available from other places as well, making it easy to switch between the builds.
Add a build queue widget to the Blue Ocean dashboard, so users could drill down into the active/pending builds with a single click.
