- Invoices should have a formal void state which merchants can put them into.
- The "Account Managers" screen should support removal of managers (other than yourself, at least).
- The "Merchant" profile screen is now somewhat inconsistent with the "Account" profile screen, and uses different icons for "Subscriptions" and "Orders".
**Add Payment Method**: This is touched on elsewhere, but it's currently very difficult to add a payment method. This is sort-of-quasi-intentional to make it difficult to //validate// payment methods, and sort-of-quasi-intentional because some payment processors may not involve real payment methods (I think the Paypal flow was checkout-only?) ,but I assume Stripe (and other processors) do appropriate sets of checks here for managing fraud, and if this is really an issue we could likely throw a rate limit on the action. You can already do it anyway (and we don't see abuse today), it's just a little tricky to find.
