Thanks, I just tested it with 3.5.0.beta9-dev (33dfd7dba9).
- The two Horizon themes still auto-enable when the forum is rebuilt. (To be sure, I rebuilt the forum an extra time after disabling them.)
- The color switcher disappears sometimes if the color palette is changed in my user interface settings. I’m not sure if that is intended.
- The small but in item #6 from my list still appears to be there. I tested it in Firefox and Chrome. It’s happening when enabling or disabling any color palette.
I’ll send you a link to a private video clip that demonstrates it.
