I don't want undermine the value of this product, but this seems like something that I've (and many others) sort of already solved by using products like Dash [1] and Alfred [2] together. You can easily and quickly find all info on docs while working right in Sublime Text, or while also using an IDE to read into functions throughout your project. And maybe I'm missing more what this product does, but that's just what I noticed based on the video.
