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). The main features that the HSV adds over the Hillside 46 are:

• nice!view e-paper display for better battery life
• Cleaner outer pinky column cut-off
• Support for a cirque trackpad with an FFC connector on the PCB itself
• Case design with support for large 750-3000 mAh batteries under the PCB
• Magnetic tenting stand with the case
• Under PCB mount for the MCU for a cleaner top display mounting
