Changes save on their own

There's no Save button on settings - change something and it's saved, with Saved ✓ beside it.

Everywhere in Hotseat, settings save themselves. Flip a switch or pick a choice and it's saved straight away; type in a box and it's saved a moment after you stop. Beside each section you'll see Saving… and then Saved ✓.

If it ever says Couldn't save, tap it to try again - usually your connection dropped for a second.
Changes that move money - a price, a commission percentage, rent - ask "Change it?" first, so nothing costly changes by accident. Cancel puts it back.
Buttons are only for doing something: Create appointment, Add service, Book, Charge, Send. Adding a card or a bank keeps its own confirm button - that's Stripe's.
