Definitely a serious project for me.  I don't intend on adding major new features from bitcoin core so there isn't much of a roadmap to speak of.  The heavy lifting is done already.

Some goals though: get listed on an exchange, get listed on coin market cap, build a blockchain explorer, discourage ASIC mining, incorporate stable changes from bitcoin public releases, fix reported issues by users.

Over time, I'll be developing an alternate Wallet GUI with JUCE, but it won't add anything new to the backend.  It'll look cooler and probably include a built-in block explorer and push button mining.
