Been playing with the free version of Rocket 3F. Love it's simple interface very much. It's underworkings are shared with NVil (formerly Voidworld). I've posted to both the Nvil and Rocket 3F forums asking what the differences are (other than UI) and I'm having a hard time in getting a straight answer.

Anyone know what the differences are in features and toolsets? I've asked a few times at the NVil forum and only received vague responses from the Istonia - creater of Nvil and co-creator of Rocket 3F.
