GreenRange

GreenRange turns your buttons RED when abilities are out of range. Several addons do this, but GreenRange is very efficient at it. It’s “green” because it’s modern and efficient, not because of the color. ? If you really like green though, you can configure it for green!

GreenRange actually has a negative performance cost, because it replaces some really inefficient code in the default UI. It’s not going to increase your framerate by more than 1, but still, it works so well that it actually improves performance vs. not having it.

Options
There’s no config UI yet, but you can use /run commands to change the colors, and the setting will be saved. These are the defaults:

/run GreenRange:SetOOR_Color(1.0, 0.2, 0.2)
/run GreenRange:SetOOM_Color(0.2, 0.2, 1.0)
