I wan to make a Jenkins (2.x) view that displays only currently running jobs (or something very close to that).
Please note that I am talking about an instance >1000 defined jobs where at a single moment we expect to have 5-30 running ones.
Looking at the node/works sidebar is far from ideal as it involves scrolling a narrow column with a height of >20 screens,... almost impossible to get a "clean view" of the situation.
You should use View Job Filters plugin which allow you to filter job view, Filter by Build Statuses of Currently building jobs.
