Spiffy
/spi'fee/ 1. Said of programs having a pretty, clever, or exceptionally well-designed interface. "Have you seen the spiffy
X version of
empire yet?"
This was common mainstream slang during the 1940s.
2. Said sarcastically of a program that is perceived to have little more than a flashy interface going for it.
Which meaning should be drawn depends delicately on tone of voice and context.
