Enhancement request: dry-run mode

[Thrutchy]

There are more ways than that to move units in what is the FoW at the beginning of the turn. Here are a few that I can think of:
* move mobi to FoW edge and teleport unit into the FoW (as you said)
* grow a chain (2+) of thorns into FoW (as you said)
* kill something that is blocking vision and move something into the FoW
* spawn something that increases vision and move into the FoW
* scramble something near the FoW and move it into the FoW

Are you saying all moves would need to be confirmed before attacking? If so, I don't think this enhancement would bring much value. Almost everytime I want to try out a different set of plays for a turn, it involves at least one attack (usually multiple). I'd like to try different ways of attacking and see what the position looks like at the end.
