I'm already used to thinking about how many sats I wanna send.
I'd suggest adding sats unit instead of fiat, or at least giving the option to switch.
I feel you. We are currently playing around with different approaches that don't "bloat" the UI. The obvious one would be a currency-switch on all payment modals, but maybe it would be better to have the user set their preferred currency in their account settings. We will figure it out!
