It would be great if the View Job Filter plugin could add a filter on the Claim status, as provided by the Claim plugin:

https://wiki.jenkins-ci.org/display/JENKINS/Claim+plugin

This plugin makes it possible for users to tell the system/other users that they are working on a fix for the failing job. It would improve our views if we then could filter out failing jobs that someone is looking into. It could be added as a check box to the Job Status filter, or a separate filter "Claim status" could be added.

The Claim status is shown in the REST API, so it should be exposed somehow an available to you.
