I really like the concept of your software but it has crashed on me a few times. It pulls in a ton of great long tail keywords and I think it does it at a reasonable speed considering what it has to do to get those keywords.
The only real thing I didn't like about the software was how quick I burned through my proxies. I have 100 private proxies and they would get banned from Google very fast when doing keyword research. I'll sign back up in a month or so to see how development has come.
Pretty good software so far.
