Kaffee-Strichliste — Nidias

Retire the paper sheet next to the coffee machine. Kaffee-Strichliste lives in the Firefox toolbar: click the icon, tap your name, and your cup is counted.

How it works
• Add people by typing a name and pressing Enter. The same field filters the list.
• A tap counts one cup. Mis-tapped? Hit "Rückgängig" (undo) or the minus button on the card.
• Every card shows tally marks in bundles of five, the count and the amount owed.
• Set a price per cup; totals update live.
• Settle up to see who owes what and start a fresh list. Past settlements stay available.
• CSV export for the coffee fund or your spreadsheet.
• The full view (button in the popup's top right) adds the last 14 days, recent activity and all past settlements.

17 themes
Light, dark, espresso, crema, high contrast and playful looks like pencil on graph paper, Stone Age notches, medieval with Roman numerals, rubber duck and vampire. Optionally switches to Easter, summer, Halloween and Christmas automatically. Press T to cycle themes.
