The windows client has the option to change the background colour of the client, it would be nice to have a dark mode option for the webtier. The windows client doesn't have feature parity with the webtier, thus users are encouraged to use the web client. Looking into white screen of the webtier strains the eyes.
There could be a new button similar to the layout picker that would switch between dark and light mode. I know that there is the option to change the CSS to accommodate this feature, but it would be nice to have it as a first party solution and be able to switch between the two modes with a toggle.
Ideally we could set the CSS as a parameter in the Branding menu.
