Enhancement request: dry-run mode

*3) since killing confirms, the FoW would change and not block vision anymore
*4) since you'd have to see where your unit is going, it requires changing the FoW so you would get the "you must confirm your moves before changing the FoW" message
*5) scrambling counts as attacking so the FoW would change

If you moved a soldier and killed the heavy, you just confirmed those moves so you can't undo the soldier moving and attacking and the FoW would change. If you see a Bombshell now, you can plan your Mobi sniper + supporting unit move + protection but you don't know what else in in the FoW. You can undo all those moves to the point the FoW last changed (soldier attacks and kills heavy). So you could spawn a runner and move it, then confirm to change the FoW and see more. If if its safe to do the Mobi sniper + supporting unit + protection move then you can proceed with the attack.
