I remember this was requested, it was impossible to implement with pure CSS but apparently you can listen on these events with javascript.
the real question is how do I mix this with current theme system without causing colossal meltdowns and butthurt all around over yet another cosmetic issue.
my plan is something like this:
- toggle night mode manual menu option is gone
- auto switch is enabled when using default.css
- add separate light.css which would force light theme just like night.css forces dark one
