Amazing work. Will bookmark.
I myself keep a detailed Excel sheet of every purchase I make, and also what I'd like to buy. For keyboards/keycaps/computer peripherals, I keep a workbook called "Compute" with different tabs for each field. GMK Esc's and artisans kept lumped together, and I give a full detailed description for each artisan--the name, the designer, the geekhack/Reddit username, the stem, the material, the height and print (if applicable), and the date I received them.
Crazy, I know, but it helps keep me in check with all my artisans and make sure they get their turn on my boards!
PS
Love the slab typeface you used; makes it easy to read!
