A Dark Theme option for this forum would be great! Not a high profile issue, but would be much appreciated. If you need help with creating a theme, I can help. Let me know on basic theme settings and I’ll test them across a Discourse forum I maintain.
If this is of interest…
Simplest bet is to add a theme selection directly with the hamburger menu drop-down on the upper left. This is exactly what meta.discourse.org offers.
Here is a simple theme component for toggling a dark mode, once you’ve setup the secondary theme.
This component will adjust the theme choice based on if you set Dark Mode in your browser.
