I think it would be very useful to have some way to find checkpoints in scenarios. There's a couple scenarios where you're given extremely vague instructions and the mission checkpoints are hard to find from your starting location. Either having the checkpoint itself point toward the next checkpoint, or giving you a compass that does the same, would be a great idea and a (relatively) simple change.
could be useful for random or scattered check point games. check points also need a chime when hit, so you know if you've "missed it by that much"
