In my personal opinion, all those people who are against @jinhao have to take into account that this is not a commercial software, so "demanding" him to focus only in nana is not a valid argument because you guys dont own anything from him.
Jinhao is taking his free time to develop nana and he can decide to stop working on it whenever he want. Nothing is going to change that. He is taking a different approach and showing up his improvements (that may or may not fall back into nana). If you just keep putting the man down on whatever he is doing, he might just demotivate in nana aswell.
Respect his choices and his free will since nobody here is buying or paying anything (besides donation, which I doubt anyone besides @qPCR4vir did it) for it.
Also, @jinhao do you have any ETA on releasing some source of the IDE? It would be good for us to see a official application developed with the expected standards of nana.
