I like to create themes of Animes or Games, I use Usagi, Yata plus has many limitations.
If you want to deepen and improve your abilities in the process of creating customized themes see this topic.
Yeah, Yaya+'s limitations are why I stopped using it. Particularly because setting up custom colors with it is abhorrent and the previews were too limited. Muuuuch easier with Usagi.
I'm getting much better with themes, though. The only thing I need to nail down is how to create custom folders and sound effects. Everything else I pretty much understand. I'll check out your guide to see what I can learn, though, thank you.
