We manage numerous visual cron connections, and sometimes people make mistakes and apply changes to the wrong connection. We would love it if we could configure different connections to have a different color. Then, when you're interacting with that server connection, the UI changes to reflect the given color. It could be as simple as the tab at the top changing color, or perhaps something more obvious. Basically anything we can do to make it obvious at a glance what server you're currently connected to.
