Shay aka wannabecoffeenerd modified mmccoyd's original Hillside and created HillSideView (HSV) with nice!view displays and many other new features.
While looking for my first ergo mech keyboard, I wanted something small with choc switches (and spacing), splay and wireless support. The Hillside 46 looked really nice but I wanted to make some changes to it including support for the nice!view, a large battery and the cirque trackpad. That prompted creating a fork of the Hillside 46 called the HillSideView (HSV) – shaysub.
