Enhancement request: dry-run mode

[Thrutchy]

OML, is it too late to ask for an enhancement that should improve the quality of game play? No rule changes.

Here is a synopsis of the enhancement: be able to do a turn dry-run that does not change the fog of war.

Here are some advantages of being able to us a feature like this:
* allows a player to visualize what there final planned position would be
* no more mistakes about miscounting wits
* should speed up plays because players can try their possible turns out visually rather than brain simulating them
* effectively gives the much requested "undo" feature

My thought on implementing this would be to have a button that puts you into a dry-run mode. The colors or graphics would be changed to designate this mode clearly. The turns could be played in this mode normally (but without confirmations). Plays could be rewound or advanced. You should be able to "commit" the dry-run turn up to a certain point and advance to the next play.

The biggest problem with this is when the turn includes attacking units in the fog. Here might be a few solutions:
* don't allow it in dry-run
* allow the player to specify the action into a fog hex when unclear - move (scrambled unit), attack, or kill
* allow the player to populate the fog the expected opponent units

Another issue to resolve is attacking vines since the parent-child relationship shouldn't be revealed with a dry-run. Here are a few solutions for this:
* don't allow it in dry-run
* gray out potential children of a killed parent. A unit can be moved on top of a potential child vine (with confirmation if necessary)
* allow the player to specify what vines are children of a killed parent
* allow the player to specify parent-child relationships up front

I assume something like this could be a paid feature.
