I would like this as well. It would help keep releases straight between groups of environments and help prevent accidents.It would provide an additional layer of assurance. It doesn't even have to be that customizable to get this feature started. You guys could just allow the change of color to header and gradually add other customizations in later.

I agree with Frank. Would be great to easily spot which instance I am working on, even if i could just change the primary colors.

Anything to allows us to easily differentiate between our Octopus instances would be very beneficial

I'd love the idea of just having a custom icon image to coincide with the branding. The little Octopus guy in the corner would be nice if we could change the color on it.

I enjoy the Octopus Deploy tools immensely, the ability to set those icons would be a nice finish.

Even Atlassian allows for setting of base icons (which really helps in differentiation of prod vs dev)

I've done some customisation via Stylebot (chrome extension).

For instance I colour projects in the dashboard

.project-name[href*=demo] {
background: #9C27B0;
color: #ffffff;
}

I would like to custom my octopus deploy page. Like i want the client images in the login and notifications for the maintenance events and support details to be appeared in main page when users opening octopus deploy home page.

I also need this ability. I need to be able to display messages to the users about maintenance windows, whom to contact internal to our organization for support. I would need to do this on the login page as well as above/below the top nav.

This would be very very helpful in helping us distinguish between multiple instances of OD.

Please implement!
