UNDO button during our turn? Feature request.

[Supergekonus]

I got a solution to your quarrels. It's a major step though.

Have a planning phase. Here all dudes pro or con can undo all they want.
Then u a confirm button and execution.

If a unit happens to be where we move, u can "else" this in many ways.
EX. Have a redo on the following moves!

Cheers
