Description

Description

Add a web content dark mode toggle similar to Cromite.

Who's implementing?

  • I'm willing to implement this feature myself

The problem

Whilst chromium has a built-in web content dark mode with various settings it is quite annoying to toggle as it requires a flag modification + re-lauch of chromium. Cromite has greatly streamlined the process with a simple toggle to enable/disable dark mode with only a page reload; could the same mechanism be adopted in UGC?

Possible solutions

Add same dark mode toggle mechanism that Cromite uses.
