Kung Fu—"In China, it refers to any study, learning, or practice that requires patience, energy, and time to complete. In its original meaning, kung fu can refer to any discipline or skill achieved through hard work and practice, not necessarily martial arts (for example, the discipline of tea making is called the Gongfu tea ceremony)." — https://en.wikipedia.org/wiki/Kung_fu_(term)
Any old filing cabinet can store your work. And your drafts. And contributions from your collaborators. And your notes.
But what if your filing cabinet could do more? What if it could travel anywhere, via the Internet? What if it helped you maintain an effortless grip on version control? Or helped you collaborate seamlessly with an endless stream of self-absorbed wing-nuts with axes to grind?
Or even better, what if it could assert your ownership of intellectual property, without you being beholden to some evil publishing company or platform? What if it could publish and promote your work aggressively, while protecting your identity at all costs? Or if it could collect cash automatically any time anyone wishes to re-use or assume ownership of your work, and then shoot the money straight into your bank account?
That'd take any filing cabinet a bit of study, learning, and practice that requires patience, energy, and time. A filing cabinet would certainly need hard work and practice, to acquire skills like those. And it'd be a real force to be reckoned with in any kind of lawyer-banker-fight. And because it's yours, all yours, it's way better than any gluttonous evil corporate publisher.
Hence, Kung Fu Filing Cabinet.
