Is there a way to set dark theme as the default for all users?

[Birdinatorx]

Hello,

I run Stirling-PDF (Docker, v2.14.2) for several users. Is there a setting (in settings.yml or as an environment variable) to make the dark theme the default for everyone?

I could not find one in the documentation.

Thank you!

From the current source there's no setting for it yet. The theme is a per-user preference stored in the browser (localStorage, key stirlingpdf_preferences), and its built-in default is "system", so users whose OS or browser is in dark mode already get the dark theme without doing anything.

The server can push some preference defaults to the frontend, which is how ui.defaultHideUnavailableTools in settings.yml works (ServerDefaultsSync in AppProviders.tsx), but theme isn't one of them. Adding a defaultTheme the same way looks like a small change, so it'd be a reasonable feature request.
