Let me put it like this...if we would take all the functions of current default Gallery and add your continues loading of images feature, then that Gallery would make sense. At the moment default or yours gallery makes no sense if you ask me. Default because we are stuck with limitation of how many images to show and in yours, all those images simply doesn't fit nicely to any of the themes, simply because the way images are stacked are design wise terrible. I am sorry if I sound a bit harsh, but masonry first of all means nothing, and the second thing, you have a great feature that is blocked by the way how gallery shows the images and that's why people don't like it. There is a big potential you just need to make some changes otherwise its hardly usable for everyone.
