It IS nice. VERY nice.
I haven't explored the full range of its features, but it is the first freeware, GUI program for OS X (that I'm aware of) that burns Disk-At-Once (DAO) audio CDs (which in plain English means you can burn a live album without having annoying gaps of silence between tracks).
As someone who has 1) been quite annoyed at iTunes's refusal to allow DAO burning and 2) continues to refuse to shell out $100 for Toast JUST so I can burn DAO, this program is enough to make me jump for joy.
The wanderfingfocus gapless-burning tutorial was a leap forward in the right direction; this program is easier, faster, and doesn't require degradation of sound quality.
