Point of sale: /pos, a per-device till mode, an on-screen pad — and off the Receive tab.

v3.coinos.io/pos opens the point of sale once a wallet is up (claimed at
boot before any feature reads the path), so the till can be bookmarked or
put on a home screen. Settings → Payments gains "Start in point of sale on
this device" (localStorage, not synced: the till, not every phone the
owner carries). The amount and the custom tip get a 3×4 pad that edits the
same field a keyboard or a paste would. The button under the payment
address on Receive is gone.
