Chrome

/krōm/

[from automotive slang via wargaming]

n. Showy features added to attract users but contributing little or nothing to the power of a system.

"The 3D icons in Motif are just chrome, but they certainly are *pretty* chrome!"

Distinguished from bells and whistles by the fact that the latter are usually added to gratify developers' own desires for featurefulness. Often used as a term of contempt.
