Please change all interfaces over to dark by default, and NEVER flash the screen white while loading
This is a very simple task, please default everything to a dark theme, please don't flash any screen white, while it's loading. I have visual problems, and the white flashing is very irritating, and the light theme is hard to focus on. I especially do not want any area of your software to show up in a light theme, when I have the theme set to dark.
This includes the settings panel, user pages, Atlassian administration, etc... keep everything in the same theme.
