Years ago I recall SexyMap included a cool border preset that was flames. Diablo style. In fact that milght've been the name? Why was it pulled? Any chance it could return? :-)

It's called "Burning Sun" and it's still there:

No, that's not it. Transparent flames extended outwards for several centimetres.

I'm not sure what a "transparent flame" is but the presets haven't changed: https://github.com/funkydude/SexyMap/commits/master/BorderPresets.lua
