SUF focuses on a simple configuration while maintaining the flexibility that most users will care about, preventing unnecessary bloating of the addon that sacrifices performance. While you aren’t going to be able to set the health bar to be exactly 3.14 pixels outside of the unit frames, you can change options you actually care about such as bar height, ordering, frame height and so on. To speed up configuration, you can configure multiple units at the same time through the global configuration. For example, if you want to set the height of the Player, Target, Focus and Party frames to 50 then the height of Target’s Target, Target’s Target of Target, Focus Target to 30 you can easily do this by changing two options instead of having to do it seven times.
However, should you need a little bit of extra configuration do not despair! An advanced option is included that will unlock additional configuration giving finer control over the configuration.
