This is really something that I am looking forward.

I am using the kubernetes recomended labels:

• app.kubernetes.io/name
• app.kubernetes.io/component
• app.kubernetes.io/instance

It would be considerably better is the card names could look like:

<app.kubernetes.io/name|app> [/ <app.kubernetes.io/component>] [@ <app.kubernetes.io/instance>]
