Though I'm sure there already is a trail on the ground showing where the character is going to move during combat?
The small dotted trail is there but, right now, it's difficult to judge how far 1 AP in movement takes you. I was suggesting adding a BIG dot in that trail to signify that you need to spend another AP to move beyond that point.
Would look something like this.
