I would like to be able to have base configuration saves in the village edit mode, say 3 saves that will keep my 3 favorite base configurations saved and easily changeable/selectable depending on what I was trying to accomplish. Say one for farming, etc, etc, etc.
I would like to be able to sell any building or item.
I would like to able to put any building in the village edit mode in a storage space. That way if I didn't want to use it in a particular base configuration, I would have it later if i wanted it. Swap from storage to active.
I think it would be neat to have clan war statistics that show's how each member is doing from a statistical point over x amount of battles. These would be rolling statistics.
Last I would like to see the option in the Clan war preparation phase that members could pre-call whom they are battling and it show's the call so they know that battle has been selected. That way you can truly prepare and build your troops for that battle without your buddies attacking the one you have planned for. It doesn't have to be set in stone, anyone could still attack that person, just a heads up that I plan on attacking that particular dude.
