This is my submission for the hackpad mission! This is my first time using KiCad and Autodesk Fusion so I'm not very experienced. Decided to make this because I wanted to make some automation easier, as it binds the keys to F13-19, which are unused usually.
It also includes a bongo cat animation, that activates when you press any key on the macropad. Code is from github over here.

Questions
How big is the Hackpad PCB?
It measures 67.1 × 78.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Hackpad use?
9 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Hackpad KiCad files?
From the nouxinf/hackpad repository on GitHub, at the commit this page was made from: the board is PCB/hackpad.kicad_pcb and its schematic PCB/hackpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hackpad design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
