I have. And I'm not worried about plugins. Some plugins do work despite the incompatibility.
But that's not to say I don't have issues with 2.3. At first, when I heard about variations, I was ecstatic. Because in my mind, it would have eliminated the whole parent skin vs child skin idea.
My biggest issue with variations is that even if you have the skin in two variations, ONE edit you make in the main variation will affect or effect the other one. I'm not joking. I already tried tinkering with variations as soon as I got "Core" (It's a name of a skin) installed on xenForo 2.3. So, you edit one part of the skin, it affects the other.
Previously, my "Core" skin looked like this:
The skin looks sophisticated. It's almost like a coder designed it. Bzz. Nope. I edited everything by hand, and asked questions. With 2.3, I got everything the way I wanted, yeah... but variations isn't so customizable at first. So when I tried adding opacity to the wrapper as you see above. As I do, light's opacity went fine. No problem. Until you switch to "dark" variation. Dark variation also had the white/white opacity! I got irritated, annoyed. So, I go back to the designer of "core" and asked how to fix the issue at hand. Turns out I had to use CSS for the
other variation!
Once I got this problem sorted. I went to another wall: I want Dark to be the main visual page of my site. There's no option to. And xenforo says they won't fix this problem!
Their reasoning was echo'ed by Brogan, and bled throughout the xenForo team like a mindvirus. Either that, or they're setting this up for xF3.
The idea of making a skin correlated to an OS "theme" is a neat innovation, and is probably inspired by a website called Umbrella Online. In one of their skins, they designed it so that when you view the site at a certain point of the day - it would change the skin. So, morning or afternoon? Light. Night? Dark. Nice innovation.
Problem: Some people like light, some people like dark. I have a market of gamers, so naturally, as you land on any one of my gaming sites, you'd expect to see a dark skin. There will be some exceptions - like PS5Forum, since it has this white/black combo.
xenForo's staff is pushing back saying "why would you force it on your visitors.?" FIRE BROGAN, OH MY GOOD LORD!
