"While going to projects' pages at github I looked up Issues in a hope to see some feature requests. But most of issues was bug reports or pull requests. I didn't want to work on bugs, I wanted more to add new features."
This is a huge problem in open source projects, and you're not alone. Throngs of developers who get off on clean, functioning code, but then turn their backs when presented with an opportunity to replace ugly and/or broken code with something better. I don't get it. Why the hesitance to engage in the pursuit of what you profess to care about?
