Note: I didn't understand how to use github until today so things probably aren't laid out properly.
It has 6 keys -> 5 switches + 1 rotary encoder switch , a rotary encoder, an OLED display and 2 SK6812 MINI - E LEDs. It uses kmk firmware and circuit python.

Firmware:
I used kmk firmware and circuit python.
I have two layers: base layer 0 and layer 1.
On base the keys are copy, paste, save, undo, mute and hold key 6 for layer 1.
While key 6 is held keys are play/pause, next, previous and a macro string saying 'sent from my Lily-Pad'
The encoder in layer 0 is volume up and down (clockwise and counter) and in layer 1 is brightness up and down.
The OLED display shows title, current layer and also it shows last key pressed.
The LEDs flash briefly when you press a key.

Questions
How big is the Macropad PCB?
It measures 63.5 × 85.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Macropad use?
20 parts, built around the SK6812MINI-E. 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 Macropad KiCad files?
From the ejfpanda/Macropad repository on GitHub, at the commit this page was made from: the board is PCB/macropad.kicad_pcb and its schematic PCB/macropad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Macropad design in my own project?
Its repository states no licence, so its author keeps all rights: ask ejfpanda before reusing the design.
