There are so many readings, and i haven't used all of them, so it's hard to know exactly what a spread is reading FOR when the card's position doesn't pop up until after you've revealed the card.
An intermediary screen listing the card positions before you move on to the spread might help people decide if the spread is right for them.
Although most readers know the Celtic Cross, I'll use as an example.
You go into Readings, general, and see the name and basic form of the spreads and brief description. When you choose one and click into it, you see the same small image of the form but with each card numbered and the positions listed with those numbers below:
1 signifier ; 2 issue ; 3 fears ; 4 past ; 5 thoughts ; 6 future etc etc
Then a button that says "get reading" or something and goes to the screen where you click the cards to reveal them.
For unique spreads like the Major Arcana or any specific topic, it can help to know if a certain spread is going to give the reader the type of insight they're seeking.
