Yeah, it was really fun to built! The parser, editor features and C# support were amazing to work on. Some times I felt like I was wasting time, but when I compare what I was working on most days in a corp to what I get to work on with QueryStorm, I'm pretty happy I did what I did. As for open source, that might be a better way to go. The project needs a community and open sourcing would help a lot. It's something for me to consider.
