change color of the "controlled by" banner

It's a bit strange you can customize the Control chat and support client window colors, but not that banner color. And would also like it to be more noticeable. Possibly even a border when screen sharing, like most other screen sharing apps.

I have had far too many clients NOT know that I have connected.

They don't see the dark grey with light grey text at the top of their screen.

If there was a bright blue bar with solid white text, that would be noticeable.

Please make this happen!
