If you hold your pointer over a move cards, there are arrows on the board showing where your character might go and what way he will be facing. If you hold your pointer over Spint, Team (or similar cards) there is no arrows, presumably because there is two characters that may move. I think there should be arrows. They could flash back and forth. First there would be arrows for your first ally, then for your second ally and so on. If there was just one ally left, there could just be one set of arrows. (even if you don't like the flashing arrows, this is good idea.) Arrows on Sprint, Team would save time since you don't have to count so much.
If it were possible to "undo" a move card, (Select it, but then put it back into the tray, which is possible in Loot and Legends) The move preview could be accomplished by hovering over / selecting characters on the board.
