My client, who is using 6346.1, is working with a “dev” and a “prod” DW instance but have several times accidentally worked in prod, thinking they were in dev.
In version 20 and older there was a great way to visually tell in what environment you were in. You could use different user interface themes and accent colors for different environments.
Unfortunately, this is not an option in 6346.1, since the theme color is not set at instance level.
Please add this feature back if possible.
