I lumped it in with the more bleeding edge distros because its goal is to showcase the latest and greatest that KDE Plasma has to offer. In that sense, it's a bit unstable on the user-facing front. Also, KDE itself is a pretty wild beast that takes a ton of tinkering to get it to any one person's liking. I'm not saying it's unusable out of the box, but it definitely is a tweaker's wet dream; its options have their own options in nearly every configuration panel.
