Aww, it looks so plain and unassuming... it needs more holes and stuff... like this one:
- 1.27mm headers on left-board edge for ROWS, COLUMNS, Vcc, Gnd and FN/NumLock LED control line (silkscreen on back)
- Adjusted spacing of 'breakway' drills - it's still hardly breakaway, you'll really need to cut it or score it a lot or something
- geekhack silkscreen
- I think I did something else, but I forget what it was
*still need to fix pad interference in the lower left there on S5 and S21... I keep forgetting about that
*might ditch that one mounting slot on the left, I just left it for alignment vs other boards
