It has been longer than a year since this package has not been maintained properly. I don't think I can keep with Atom's development cycle. I also faced a performance issue as the size of text files grow, making this package less and less usable.
I also appologize the ambiguous naming for nvatom, which is short for Notational Velocity for Atom. Zachary Schneirov, the creator of Notation Velocity, contacted me that some people may mistakenly believe that this package is an official component or sub-project of Notational Velocity. I want to make it clear that this project was NOT affiliated with Notational Velocity.
Thanks a lot for your interests and contributions.
