We have completely different installations of TM for prod and test. Since we upgraded them so they are both the same version, we find it confusing that they have the same favicon.
I know how to update the favicon for spaces, but can you do it for TM too? Is there any way to add it the Admin Environment CSS style in the module properties?
I tried locally, there's a way changing the pic file in assets (/manager/assets/skin/favicon-manager.ico), but if it's AWS, managed by hosting, I don't thing there's a way to do it without hosting team intervention.
