My company uses Elasticsearch and Kibana for various reasons. One of my responsibilities is to ensure the stability of our elasticsearch test and production cluster. My users and me have problems to distinguish the various environments (test and production). It happen more than once, that I executed an action with Sense/Console in the wrong environment :anguished:. To make a better distinctive appearance, I dug a little in the Kibana source around and found it no so hard, to alter the appearance.
