Could you explain the use-case a bit more? What would you do if you see a "new changes arrived" indication? Start the build manually?
Not sure if you saw this, but a new plugin has just been created yesterday, that seems to fit your description:
https://wiki.jenkins-ci.org/display/JENKINS/Pending+Changes+Plugin
Maybe this plugin already has some sort of notification (eg. Email) built-in. This could be faster and simpler than manually checking an indication in a column. Or it provides a common interface that can be used by other plugins.
