Currently there are 3 formations: Horizontal, Vertical and Bottom.
In the app I'm working on, I use two of this view side by side to enter a currency amount. The left one is for the dollar amount and the right one for the cents. The formations selected are bottom for both of them.
The left view's "-" sign is very close to the right view's "+" sign and when you try to hit one of them, you could easily press the other by accident. They together represent a single currency amount, so it makes more sense to keep them side by side than separating them by enough space.
A solution: Top formation for one and Bottom formation for another.
