I find it very frustrating to not be able to assess battle statistics without first moving and then, upon doing so, realizing that attacking across the Maginot with my 0 Effective 1 strength Garrison isn't a good idea and then having no chance to take the move back. I get this for FOW games but this seems like a glaring omission otherwise. Is there any mod available for this? Thanks.

Also, how does one search a forum on here - don't see the option anywhere.
