There is a reaction phase at the start of your turn, and before the other player's combats take place. So they move, then you get to do some limited reaction moves, then their combat takes place, then you move, then they have limited reactions and then your combat is resolved. No editor, sorry, although IIRC much data is stored in .txt files that can be altered if you want, including creating new scenarios.
All understanding comes after the fact.
