To Assign fielding positions in the lineup screen is very time consuming. Open the player, select their position, save, click next player repeat.

Once we have a player open, maybe we would be able to swipe to the next player, similar to the way you browse pictures?

On iOS devices, you can tap the position selector right from the lineup list. You don't have to open the player. If you are using an Android device, this feature will be added in a future version as well.
