iOS app needs sticky headers for Exchange names/balances

[cjdowner]

Feel free to close because I don't know what the latest is with the cards - but when scrolling, all your accounts / cards are just a single list.

In the Mac app for example, the card titles showing the exchange logo and your balance sticks to the top when scrolling. That's quite nice and it feels missing here.

I think rather than making the header sticky, you make the card sticky. They're stacked on top of each other so that would work so nicely

Hey sorry, just seeing all these (they were at the bottom of the backlog list).

We thought about making the cards sticky but then the problem is that if a card has too many accounts it would go past the bottom. We get the sticky headers for free on Mac because it's just a table view. With the cards it's a custom collection view which makes that more difficult (though potentially not impossible).

We actually wanted to eventually move to the same cards design for macOS, the tableview was just a compromise for 1.0 since it already worked.

Leaving this issue open to investigate improving the cards design.
